摘 要
本设计包括三个部分：一般部分、专题部分和翻译部分。
一般部分为乌鲁木齐碱沟煤矿0.9Mt/a新井设计。碱沟煤矿属于神华新疆能源有限责任公司。井田走向长度平均为2.208km,宽度为0.968km,平均井田面积为2.137（km2）。井田内主采煤层为两层，即43、45号煤层，平均倾角84°，煤层平均厚分别为51.36m、31.32m，井田工业储量为10125.91万t，可采储量7522.52万t，矿井服务年限为64.30 a。
矿井开拓方式为斜井二水平开拓，主井，副井为斜井，风井为立井，全矿布置有首采一采区，二采区及三采区。主斜井倾角15°，全长740m,装备带式输送机，副斜井倾角20°，全长508.7m,装备双钩串车；风井净直径5.0m,井筒深度42m,装备玻璃钢梯子间。 称交生产时，在43号煤层布置一个综采工作面，一个连采采掘进工作面和一个普通掘进工作面。连续采煤机还能进行煤柱回收和回撤巷道煤柱回收。工作面长度为51.36m，年推进度为1320m。日产量为3000t，通风方式为中央分列式。
矿井主运输采用带式输送机，煤从采煤工作面到地面实现连续运输；矿井斜井辅助运输采用双钩石门采用电机车。
矿井年工作日为330 d，每天净提升时间16 h。矿井工作制度为：实行―三八‖制。 专题部分题目：急倾斜10m-20m大放高研究。
翻译： 英文原文题目为：Combustion of Coal Mine Ventilation Air Methane in Thermal Reverse-flow Reactor
关键词：新井设计；急倾斜水平分层放顶煤；中央分列式

ABSTRACT
This design can be divided into three sections: general design, monographic study and translation of an academic paper.
The general part is a new design of Urumqi jiangou coal mine coal mine,which produces 0.9Mt per year.It belongs to Shenhuan group of Xinjiang .The length of the north-south direction of the coalfield is 0.968km and the east-west direction length is 2.208 km,so its area is 2.137km2.The main coal seam which I design is No.43 and 45 coal seam ,which dip angle is 84 degree,51.36 and 31.32m for its thickness.The proved reserves are 101.25Mt and the recoverable reserves are 75.22Mt,and it can work 64.30years.
The way to open up the mine is the shaft double horizontal development.The main shaft and the auxiliary shaft are inclined ones,but the air shaft is not.We open up the No.1 district ，No.2 district and No.3 district on the whole mining area.
The dip degree of the main shaft is 15 and auxiliary one is 20.Thelength of the main shaft is 740m and the auxiliary one is 1507.8m.The diameter of the air shaft is 5.0 m and its length is 42m.
When produced,we arranged a working ,a continuous miner heading face and a general heading face.The length of the working face is 51.36m and its continuous promoting length is 1320m.It produces 3000t every day.
The way of the major transport is belt conveyor and the auxiliary transport is the double train vehicle.They can realize continuous transport。
We work 330 days per year ,and exaltate 16 hours one day .The ―three–eight‖ working system is applied for coal mining .
The monographic study is The study of 10m-20m steep dip coal mining top-coal caving. The translated academic paper is about Coal Mine Ventilation Air .Its title is that Combustion of Coal Mine Ventilation Air Methane in Thermal Reverse-flow Reactor
Keywords：the design of mine; steep dip top-coal caving ; centralized juxtapose ventilation
