采矿工程专业毕业论文--鹤煤十矿0.9Mta新井设计（煤矿瓦斯治理技术研究）.doc

摘要
本设计包括三部分:一般部分、专题部分和翻译部分。
,共分十章:矿井概述及井田地质特征,井田境界和储量,矿井工作制度、设计生产能力及服务年限,井田开拓,准备方式—带区巷道布置,采煤方法,井下运输,矿井提升,矿井通风及矿井基本技术经济指标。
鹤煤十矿距鹤壁市市区6-13 km,矿区对外交通便利。区内地势较为平坦, km, km。 km2。井田主采煤层为二1煤层, m。煤层倾角平均为23°,属于缓倾斜煤层。
,。,矿井, m3/min。矿井为低瓦斯矿井。
鹤煤十矿矿井工作制度为“三八”制,一个综方工作面保产。开拓方式为立井两水平直接延伸,水平标高分别为-340 m,-500 m,准备方式为采区巷道布置。矿井主井采用箕斗提煤,副井采用罐笼作为辅助提升。工作面采用长壁采煤法,面长150 m,采煤工艺为综采。矿井主运输为胶带运输,辅助运输采用架线电机车牵引1 t固定式矿车运输。矿井通风初期采用中央并列式,后期采用中央分列式。
专题部分题目是煤矿瓦斯治理技术研究。论文对瓦斯的抽采、抽放技术研究进行了综述,分析了我国当前形势下的各地区煤层气分布情况,针对各地区不同的地质情况,应采用的瓦斯抽采、抽放技术、治理的方法。并对现场应用情况进行了效果分析。
翻译部分对综放沿空掘巷卸压技术进行了介绍,其英文题目为Study on destressing technology for a roadway driven along goaf in a fully mechanized top-coal caving face。

Abstract
This design contains three parts:the general part,the special part and the translated part.
The general part is a new design of Xu Chang mine belonging to Zi Bo mining bureau whose production capacity is Mt per has ten chapters as follows:the outline of mine and mine field geology, boundary and reserves, working system and productive capacity and service life, development method of the mine, the main roadways, coal mining method and layout or roadways in working area,transportation of underground, mine lifting, mine ventilation and safety, main technique—economic induces.
The Xu Chang mine filed lies in the north of Ji Ning about 8 transportation is convenient covers square kilometers. The boundary of the minefield run kilometers on the strike and the pitch length is three is the main coal seam,its dip angle is 4 degree and thickness is about 3m on average.
The proved reserves of the minefield are million tons,and the recoverable reserves are million tons. The designed productive capacity is million tons percent year, and the service life of the mine is years. The normal flow
