China, the former Soviet Union, the European introduction of the long wall coal mining law, the United States, Australia, South Africa, India and other countries are mainly short wall coal mining law. France long wall coal mining output for 70% of world coal production.Since the 1960s, most coal mining conditions from deteriorating state, such as the German coal mining depth from the 1960 average of 726M to 927M 1995, the largest-1443M, the rock temperature was as high as 43 degrees. Several countries pit mining depth table 1-1. Coal production is oil and natural gas (cost off cheap imported coal for the country is) competition and increasingly stringent environmental regulations restricting the use of coal quality retinue to set higher requirements. On the other hand, microelectronic technology and technology at the core of his high-tech rapid infiltration to the coal industry. Both factors contributed to mine coal mining technology innovation. At present, coal mining is integrated mechanized mature technology; Microprocessors, computers and expert systems applications, and rocks control theory and technology to improve and further enhance the operational safety and production efficiency. Developed countries are applying the research and development of a new generation of automation and robotics Underground coal mining systems. 2underground mining development trends (1) enlarge Experience has shown that in certain mining conditions, increased mining intensity is the main way to improve the economies of scale effect, and the Integrated Procurement of equipment to enhance production capacity, creating conditions for the expansion of the size of mine. Currently, a mining equipment Integrated largest production capacity has reached 3500T hours daily output can be maintained at 10000T above. Therefore, the annual number of new mine capacity to 3-4MT. Research a long wall located rapid advance to a district length increasing, the United States averaged 1996, 2570M, 1874M Australian average, the worlds largest-5365M (United States). Is much more than the length increase to 200M, 251M 1996, the average American, German 277M, 354M for the largest. This is a coal mining methods to promote innovation, such as using more long wall, turning to mining, a rotary workers, non-coal pillar mining. (2) focused production. Mine production is increasing production efficiency and effectiveness of centralized key factor is the main way to the conversion of existing coal merger, the closing uneconomic mines, the new high-yield, and efficient pit. Germany in the period 1965-1995, the number of mine production reduced to 19 by 107, the average annual per mine to 2.79MT from 1.26MT, the average efficiency of coal-raising call from 2.705T/ 5.587T/ workers. Concentrated production of the key issues is to ensure that equipment and system reliability, as well as the coordination between the production chain. This requires addressing a range of technical and management issues. (3) streamlining the production system. Comprehensive mechanization in the coal mining basis of extraction integration, further simplification mining processes; Thick coal bed once a high-grade mining replace; Using powerful tape carriers for the transport of the entire mine, reduce reproduced; Using single-track suspended, or no-card-car vehicles of equipment, materials, located directly transported; Simplified street layout, one lane use; as a quasi-open pit mining in the coal bed. 3coal mining equipment Over the past 10 years, mining coal mining equipment and control systems have great progress, the main trends are : （1）adaptation.Caimeiji can exploit thick 0.556.0m, inclination 60 meridian east of the coal bed. Modular design for factory under specific geological conditions shaft provide dedicated products, and ease of maintenance. （2）large-scale. To enhance the capacity and reliability of all coal mining equipment size, weight and power are tending to increase. Currently, the maximum weight has reached 90t Caimeiji since moved cradles of 50t/ aircraft. Germany Yikefu companies SL-500-Generation Caimeiji total power of 1508kW, 5000V power supply voltage, a high 2.25.0m. German production since moved supports for the coal bed 0.556.0m, Hemuxiate company produced two pillars for the United States strongly supports cover style, resistance to 8900kN. China and the former Soviet Union has a 10,000-strong chamber of thick coal bed frames. Cradles into Group (615 helicopter) - fluid control has become a standard control system, time-8s have one of the following. Shun bed in the remote control system has been used in the production of microprocessors. High-yield, located a zone tape carriers largest transport capacity has reached 3500t/h, power 1400kW, bandwidth 1.51.6m, belt speed 3.54.7m/s greatest level of bank 2000m (more driven), automatic control technology has reached a very high level. The biggest part of the largest weighing 120t boring machine, the first cut off power to 500kW, cutting compressive strength than 100Mpa rock, the largest known flood 70m. （3）control and automation. Britain, Germany and the United States in the underground pit remote control and automation considerable research, the ultimate goal is to achieve the automation coal mining was not always work. Currently, the sensors will be measured down to the ground computer data transmission network multifunctional working environment monitoring systems, has applied. Caimeiji, since moved cradles, boring machines, tape carrier aircraft to the remote control and automation equipment Shan Taiwan technology matures. Located throughout the remote control and automation have made clear progress, the British rock boundaries of the natural radioactive gas sensors has sold more than 300 domestic and foreign. U.S. Bureau of Mines has the fully automatic continuous Caimeiji initial success of the test. British research and development of automated systems is a long wall located model, only one class and one control inspectors. Automation, located birth is not far off. The status and health monitoring equipment at the basis of microprocessors has developed a computer-based mining and coal dressing plants and the whole process of monitoring and control system. British Minos systems have been successfully used in many mine. Future computerized pit, allowing human than the current 75% reduction. 4a comprehensive investigation located According to the U.S. coal Era, 1996 a total of 12 major coal country, located 1,759 Integrated Procurement these long wall mining wells in the production of the Integrated 905Mt, accounting for 27% of world hard coal production, 5, high-yield and high efficiency is much longer （1）high-yield located Currently, 1 million tons of annual Integrated Procurement located is widespread. America in 1994 with an annual average of 1.58MT Integrated Procurement located, the highest level. 54MT; average efficiency 281.2T/ work.
