平煤二矿1.8mt摘要

1、摘要本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分共包括 10 章：1.矿区概述及地质特征；2.境界和储量；3.矿井工作制度、设计生产能力及服务年限；4.开拓；5.准备方式带区巷道布置；6.采煤方法；7.井下矿井基本技术经济指标。；8.矿井；9.矿井通风与安全技术；10.一般部分为平煤二矿 1.8Mt/a 新井设计。平煤二矿位于省平顶山市，交长约 4.9 km，倾向长约 5.2 km，总面积为 25.48km2。主通便利。采煤层为四 1（戊 ）煤，倾角 317，平均 8。煤层平均厚度为 3.45 m。210地质条件较为简单。工业储量为 197.18Mt，矿井可采储量 159.32

2、Mt。矿井服务年限为 63.2a，涌水量不大，矿井正常涌水量为 548 m3/h，最大涌水量为 1070 m3/h。矿井相对瓦斯涌出量为 5.94 m3/t，为低瓦斯矿井。根据地质条件，提出四个技术上可行的开拓方案。方案一：立井单水平上下山（岩石大巷）；方案二：立井单水平上下山（煤层大巷）；方案三：立井两水平暗斜井延深（岩石大巷）；方案四：立井两水平暗斜井延深（煤层大巷）。通过粗略和详细技术经济比较，最终确定方案一为最优方案。一水平标高-430m，整个划分为 2 个带区和 2 个盘区。矿井采用 矿井采用带区式准备方式，工作面设计长度全高采煤工艺。矿井年工作日为 330d，昼夜净并列式通风方式。

3、200m，采用综合机械化一次采时间为 16h。矿井采用“四六”制工作制度，三班生产，一班检修。循环进尺为 0.6m，日产量为 5402.7t。专题部分题目为浅析巷旁充填技术的研究与应用。翻译部分题目为 Geotechnical considerations：新井设计，立井，单水平，带区，ine backfilling in Australia。并列式ABSTRACTThe three parts is includedand translation.his design,i.e.,teral part, spel subject partThis general part includes t

6、inefield is 4.9 km ,the width is about 5.2 km, well farmland total area is 25.25 km2. No. 4 are the main coal seam, and its dip angle is 217, 8 for average. The thickness of the mine are about 3.45 m. The geological conditions of the minefield is relatively simple. The proved reserve of the minefiel

The relativegas emisrate of the mineral well is 5.94 m3/t, for low gas mineral well.Based on the geolog

The design length of working face is 200 m, which uses fully mechanized mining with full-seam mining technology. The wor

11、king days in one year are 330. Everyday it takes 16 hours in lifting the coal. The operation mode in the mine is“four-six” with three teams mining and the other overhauling. Every mining teammakes three working cycle, and the overhauling team makesorking cycle. Soeveryday there are 6 working cycles. The advance of a working cycle is 0.6 m, and thety of 5402.7 ton coal is maked everyday.Spel subject part of topics is:ysis the study and applicatioon of roadsidepacking technology.The translated academi
