罐子沟煤矿120万吨新井的设计（机械CAD图纸）.doc

摘 要 本设计包括三部分：一般部分，专题部分，翻译部分。 一般部分是罐子沟煤矿120万吨新井设计。全篇共分为五章：矿井概述及井田地质特征、井田开拓、采煤方法及带区巷道布置、矿井通风、矿井安全技术措施。 罐子沟煤矿位于内蒙古鄂尔多斯市准格尔旗境内，井田总面积6.24 Km2。主要可采煤层（4-2中，5-1上、5-1、6-1上、6-2中），可采煤层总厚度.88m。煤层倾角平均为2°。井田工业储量为143.3Mt，可采储量97.6Mt。正常涌水量为/h。相对瓦斯涌出量0.34 m3/t，因此为低瓦斯矿井。煤层属低挥发分，煤尘不具有爆炸性，煤层无自燃倾向。 罐子沟煤矿设计年生产能力为120万t/a，服务年限为62.6年。矿井工作制度为“三八”制。矿井的采煤方法主要为倾斜长壁综合机械化开采。矿井开拓方式为斜井单水平开采。 矿井布置一个回采工作面生产，一个备采工作面，一个掘进工作面，年生产能力为120万t/a。工作面长度为160m。运输大巷采用胶带运煤，大巷辅助运输采用无轨胶轮车运输材料、人员和矸石。矿井通风方式为中央并列式，全矿总需风量为3525 m3/min，通风容易时期等级孔为3.31㎡，困难时期为2.02㎡，均属通风容易矿井，主要通风机为62A14-11-No24轴流抽出式风机。 专题部分为“云南私庄煤矿特大突出事故的原因分析”。 翻译部分为“煤炭自燃”。 关键词：罐子沟煤矿； 开拓； 煤层； 通风； 矿井； 灌浆 ABSTRACT The design includes three parts: general, thematic elements, some of the translation. The general part is a 1.2 million ton design of guan-zigou colliery. It contains five chapters: summarize of the mine field geological character, mining field deploitation, the excavating coal method and disposal of laneway in mining area, ventilation, technology of mine safety. The guan-zigou colliery lies in zhun-geercity of the Inner Mongolia Autonomous Region . The total area of the mine is 6.24 km2. Five layers can be mainly coal mining（4-2middle，5-1above、5-1、6-1above、6-2 middle） the average thickness is in turn 16.88m. Its obliquity is 2 degree on average. The industry reserves of the mine field are 143.3 million tons and the useable reserves are 97.6 million tons. The normal effusing water of mine is 30 m3/h on average. The comparative effusing of gas is 1.63 m3/t , so it is a low- gass mine. The volatilization of the mine is relatively bigger, there is not the danger of exploding on the grime, the coal not has spontaneous combustion tendency. The design throughput of mine is 1.2 million tons per year, and it’s service life is 62.6years. The labor system of the mine is “three-eight. The main methods of mine coal for comprehensive mechanized mining inclined longwall. Mine exploit way more horizontal band area for inclined drilling。 There is one working face
