These bilateral links to various functions AFC Coal conditions, the use of a wider scope, the disadvantage is that there are two bilateral chain linked Shouli Bu absorbed phenomenon. Three bilateral links in the chain scraper conveyor developed on the basis of When the two chains not enough strength, an increase of a middle chain, the practice has proved that such a structure chain Shouli Bu absorbed form of the phenomenon than the bilateral chain scraper conveyor more serious, frequent Duanlian accidents, products are eliminated. Two-center chain-type compared with the bilateral links, the chain of uniform, bending performance advantages, but in the hard coal! Meikuai circumstances of the larger transportation to perform well. Small scraper conveyor single chain of more, but with the large-diameter circle in the chain, the chain increased strength, the German use of large-diameter circle of chain-linked heavy AFC, this form of chain conveyor To bear the load in the same circumstances, than the double-stranded chain of specifications to be larger.a) Scraper conveyor of the transmission capacity must be equal to or greater than Shearer or the production capacity of coal plough. But Shearer face conveyor and the productive capacity of roadway with the mining area, transport roadway and upgrade the mines transport capacity of the infrastructure, the ability to prevent face-off, mining area or roadway and a lack of transport capacity Kabo Ziphenomenon. Scraper conveyor structure and form of traction Shearer, and walk-oriented institutions! Bracket and the end of Slipper of the supporting structure;b) Scraper conveyor length of the chute and hydraulic support to match the widthc) Scraper conveyor of the chute and hydraulic support the passage of the jack and connect devices with space to match;d) Conveyor of the chute to rugged wear-resistant structure, a flexible;e) In order to reduce Duanlian accidents, linked ring in the large-diameter, high-intensity direction;f) Priority choice of two-motor-driven double-nose, to reduce the transmission size, the largest chain to reduce tension, reducing the nose and tail of the top area of control. Selection of priority short nose and short tail, but the head-and tail-in or corner of the plate should not be too large to reduce the pressure in the chain block friction loss.2 Reversed loader lectotype of principleBridge reproduced machine is actually a special structure of the heavy scraper conveyor, in the face conveyor section Pingxiang and scalable conveyor belt between the role of a reprint.a) Reprint of the transportation capacity to be slightly larger than face scraper conveyor. To this end use of increased chute section(on both sides of the chute and baffle), increase speed linked(to change the second-reducer gear transmission ratio) or shorten the distance between scraper, and other measures;b) Reprint of the gear in the nose of uniform, should be based on volume and distance to determine the size of the electrical power and the number of Taiwan. Priority should be optional single-motor drive, when the volume and greater distance, the optional dual-motor drive. Its transmission should try and face the same scraper conveyor to GM;c) Reprint of the aircraft tail and face the conveyor connected to the matching. A lap and non-overlap in two forms, regardless of what form, should ensure that face scraper conveyor nose of a certain height unloading(normally600 700 mm),in order to avoid face-scraper conveyor Linked to the end of coal;d) Reprint of the nose are loaded walk in the small car, walking the structure and gauge car with retractable belt conveyor tail-supporting;e) Reprint of the bridge deck and the Department of retractable conveyor belt of coal by the tail of the length of the overlap should be complementary;f) Machine parts and reproduced the face scraper conveyor should do everything possible to GM, to facilitate the supply of spare parts and maintenance.3 Retractable belt conveyor of the principle of selectionScraper transport planes from the coal face, reproduced as bridge-to-trough uninstall the retractable belt conveyor, and then coal from Pingxiang transported to the section on the downhill or with the station. With the face of advancing to the section Pingxiang transport equipment to a more flexible elongate or shorten. Retractable belt conveyor is characterized by a set of certificates with its devices, this device from the temporary storage tape from the appropriate role, when the mobile tail, the reservoir with a corresponding device can be released or save a certain length of the belt.a) Mining machine with the transport section of Pingxiang general optional retractable belt conveyor, and its production capacity to match reprint machine. According to choose a suitable throughput with bandwidth and speed;b) Retractable belt conveyor for the laying of the general length of 500 1000 m-Taiwan, when a length of two series can not. Can also choose multi-driven conveyor belt, the length of up to 2000 3000 m;c) Conveyor belt transmission device generally used double-drum drive, and priority should be optional single-motor drive, to avoid the load due to the electrical transmission equipment caused by the unequal distribution of power increases. When the single-motor power shortage# optional two-or three electrical transmission;d) Storage devices with the activities of a drum, two and three(corresponding certificates with a two-tier, six and four storeys) should give priority to the simple structure of single-cylinder structure. If the reservoir with a shorter length of the warehouse, they can choose two or three roller structure;e) Tighten the structure of a device automatically tighten (adjustable tensioning force) and non-automatic tensioning device two categories, priority should be given to choose the former, to ensure that the tape is the appropriate tension;f) Transmission drum machine or a head band of anti-skid tape and driving drum 9 skid) security installations and non-security devices are to choose the former, in order to prevent the tape skid cause serious damage or excessive temperature rise caused by adhesive tape on fire Incidents. Ordinary canvas with a belt and high-strength nylon with two batteries, should try to choose the latter, to reduce the thick belt, increasing distance. Tape a general belt and fire tape, the latter should be used to prevent fires.g) Shift the tail installed with hydraulic and electric winch-and Fully-supporting, a pumping station system for emulsion priority should choose the former, no pumping station system can choose the latter;h) Retractable belt conveyor by the tail on the length of the form and structure to be reproduced with the bridge of the bridge and walk the length of the overlapping structure of the Department of match;i) Retractable plastic belt conveyor structure of the body-hanging wire rope, steelHanging-beam steel frame and floor-variety. Type of steel wire rope hanging with little, simple equipment, suitable for floor changes, easy to water conditions, but the operation to shorten the tail relatively trouble. Steel-framed floor-simple structure, demolition of convenience, is conducive to the use and maintenance, but the fuselage large amount of steel used, the floor changes have an impact on the rack, under specific circumstances appropriate choiceCape pushing high-grade coal face in the course of mining, will often encounter some fault ramps National Chiao Tung University(H 3m)-not pushing too hard, making a face similar to the faultsystem between thetriangle-shaped pillar,the pillar under the triangular Fault can be divided into the direction ofbeing triangle and theinverted triangle of two. More recycling of coal resources, the inverted triangle coal-mining, are often used along the fault trend, retaining a fault-coal, transport, dig a supplementary entry, face additional transport along the roadway normal progress, but added the roadway and transport planes To retain a mining method, that is reproduced after the maintenance of mining.It is the most important feature: the direction of promoting the face of coal and reprint the opposite direction. The dig-mining technology to the maintenance of mining after another development, it mainly refers to one side of boring mining Lane added transport, mining technology is a supplement.1 After the set of maintenance and exploitation of the significance of the dug-mining applicationsThe work in front of the National Chiao Tung University inclined to expose fault, not hard-pushed the inverted triangle formed coal-mining, there are two under the conventional mining method: wear-mining and mining. -Will often result in-prone forward, the old waste pond falling keep up with all the top row, back-to bring greater difficulty and lower efficiency. When the old pond and a hanging roof suddenly falling, it will cause massive waste overturned cut the top row pillars, a spray men Zi phenomenon, to bring greater security threat. So for mining, mining face prone to a certain level will not be able to continue to promote the coal recovery rate is not high. The recovery of lower coal mining wear, can only reach60 percent, the same need to fill the excavation, Lane added, using artillery and mining will consume a large amount of explosives, detonators high costs, risks, prevention-management is also very difficult, there More hidden dangers. By comparison, a reprint after the maintenance of mining coal mining face can guarantee the normal advance, and can increase the recovery rate, the districts high yield and high efficiency to promote the building of a higher value.Under normal circumstances, reproduced in the former mining machine after maintenance, ahead of meeting the need to add the roadway excavation and the laying of good reproduced directly to the recovery teams used, which would involve tunneling unit of energy, the occupation of certain human, material and Supporting material from consideration, construction of the tunnel boring the general-shelf support, and a steel support. In the latter role in maintaining pressure on the roadway, the steel roof will be a lot deformation, it is difficult to retracement, but can not reuse, then try the coal-mining teams from their own side tunneling transport Lane added, while maintaining a post-mining method, that is- Mining excavation techniques. Construction used hydraulic prop legs to replace the steel shelf-shelf support, a flexible support, reducing the pressure on the roadway, improve the supporting effect.2 Reprint after the maintenance of the technical requirements of mining With the face forward, added the roadway, while retaining the support not back, on top of the alley, along the direction of the dumping Dou reservations Face the bottom of the first three rows of regular pillars. To reduce air-side of falling coal pillars of pushing pressure, three rows of stranded in a timely manner to the use of hinged roof beam to the pillars, roof beam along the tendency to use the hinged support, a pillar of the reform may not be behind all face Top ranked. After the maintenance of Zhu Liang to set up, the first branch after the change, post-wear Muxie established to reduce the latter part of the pillars of the end of drilling. Reprint of the above two rows of pillars as sidewalks, width of1. 0m, the spacing between the two groups Zhuliang to1. 0m, most Shangyi Pai pillars and columns to file additional intensive pillars to prevent channeling rock. After the maintenance period to reduce the pillars of the deformation, tofacilitate the work of retracement along the roadway after the maintenance of the pillars of Shangyi Pai, located at8 m with a wood pile to strengthen support and maintenance of the roadway after the hand for cleaning up to ensure that the roadway Height of not less than1. 6m.Development prospectsWith the coal mining life of the reduced recoverable reserves of less and less, and with the deep development, more and more complex geological conditions, 1.30, in more and more coal, therefore, how the limited resources, improve the coal recovery rate, And to resolve theTo follow the more mining, will be in a very long topic, so for high-end after the maintenance of general mining and mining-excavation and mining technology provides a broad prospects for development, the promotion of a certain value.中文译文采煤工作面运输设备的选型及刮板转载机选型介绍摘要：采煤工作面运输设备的选型对采煤工作面的生产有着重要的影响,本文介绍了各类刮板运输机、刮板转载机、可伸缩胶带输送机的技术特点、适用范围以及如何选型。关键词：输送机；选型；能力；原则1采煤工作面刮板运输机的选择按牵引链的数目及布置方式可将刮板输送机分为单链、边链、中双链和三链等4种类型。其中边双链刮板输送机适应性强，可用于各种煤质条件，使用范围很广，但缺点是边双链会出现两根链受力不匀的现象。三链是在边双链刮板输送机的基础上改进而来的，当2条链子强度不够时，中间再增加了一条链，实际证明，在这种结构形式中，链受力不匀的现象比边双链结构还要更严重，常常发生断链事故，近于淘汰产品。中双链链型与边双链型相比，有着链条受力较为均匀、弯曲性能更好的优点，但是在煤质较硬、煤块度较大的情况下运输效果不是很好。小型刮板输送机主要以单链型的结构较多，但随着大直径矿用圆环链的出现，链条强度逐步提高，德国大多采用直径较大的圆环链的单链重型刮板输送机，该种形式输送机的链子在承受相同载荷的情况下，要比双链型结构所用的链规格要大。a)刮板输送机的输送能力必须等于或大于工作面采煤机或刨煤机的生产能力。但工作面输送机及采煤机的生产能力要与采区巷道、运输大巷、整个矿井的运输提升能力相配套，以防采煤工作面能力过大，采区及大巷运输能力不够而出现“瓶颈”现象。刮板输送机的结构形式必须与采煤机的牵引力机构、行走及导向机构、底托架及滑靴等部件相配套；b)刮板输送机的溜槽长度要与液压支架的宽度相互匹配；c)刮板输送机的溜槽与液压支架的推移千斤顶的连接装置和配合间隙要匹配；d)输送机的溜槽结构要同时具有坚固和耐磨的特性，还得具有可弯曲性；e)为了减少断链事故的发生，圆环链逐渐朝着大直径、高强度的方向发展；f)尽量选用双电机双机头驱动方式，从而减小传动装置尺寸，降低链条的最大张力，减小机头部和机尾部的控顶面积。尽量选用短机头和短机尾的刮板输送机，但机头架和机尾架中板的升角不应过大，从而减少在压链板的摩损。2刮板转载机的选型原则刮板转载机实际上就是一台结构特殊的重型刮板输送机，在工作面刮板输送机与顺槽巷道可伸缩胶带输送机之间起到转载没煤炭的作用。a)刮板转载机的输送能力要稍大于工作面刮板输送机。为此多采用加大溜槽断面(在溜槽两侧加挡板)、加大链速(改变减速器内第二级齿轮传动比)或者缩短刮板间距等措施，来实现这一要求；b)转载机的传动装置均布在机头，应根据运量的大小及运距的大小来确定电机功率和台数。应尽量选用单电机传动，当运量和运距都较大时，可选用双电机传动。其传动装置应与工作面刮板输送机保持一致，便于在使用中做到部件通用；c)刮板转载机的机尾部与工作面输送机的连接处要配套。主要有搭接和非搭接两种形式，无论采用上述哪种形式，都应保证工作面刮板输送机机头有一定的卸载高度(一般范围600 700mm)，以避免工作面刮板输送机机底链存有煤；d)刮板转载机的机头均要，装在行走小车上，行走小车的结构及轨距必须与可伸缩胶带输送机机尾部配套；e)刮板转载机的架桥段与可伸缩胶带输送机的机尾受煤部的重叠长度应配套；f)刮板转载机的零部件与工作面刮板输送机应尽可能通用，以便于备用零部件的供应及维修。3可伸缩胶带输送机的选型原则由工作面刮板输送机运出的煤炭，经刮板转载机转载到顺槽巷道的可伸缩胶带输送机上，然后把煤炭从区段平巷运到上下山或装车站。随工作面的前进，区段平巷运输设备必须能够比较灵活的伸长或者缩短。可伸缩胶带输送机的功能特点是它有一套储带装置，这套装置起暂时储存起适量胶带的作用，当移动机尾时，储带装置可相应地放出或储存一定长度的皮带。a)机械化采煤配合的区段平巷运输一般选用可伸缩式胶带输送机，其生产能力要与刮板转载机相匹配，根据输送量选择合适的带宽和带速；b)可伸缩胶带输送机的铺设的长度一般为500 1000m台，当一台长度不够时可串联两台。也可选者用多段驱动的胶带输送机，其长度可达2000 3000m；c)胶带输送机传动装置一般采用双滚筒传动,且应尽量选用单电机传动,从而避免由于多电动机传动带来的负荷分配不均的现象，造成设备功率增大.当单电机功率不足时，才可选用双或三电机传动；d)储带装置的活动滚筒有一个、两个和3个(相应储带两层、四层和六层）尽量选择结构简单的单滚筒结构。若要求储带仓部分胶带长度较短时，则可选用两个或3个滚筒结构；e)拉紧装置的根据结构形式共有自动拉紧（可调整拉紧力）和无自动拉紧装置两类，应尽量选用前者，以保证胶带具有
