摘要
本设计包括三个部分：一般部分、专题部分和翻译部分。
一般部分为小鱼沟煤矿1.2 Mt/a新井设计。一般部分共包括10章：1.矿区概述及井田地质特征；2.井田境界和储量；3.矿井工作制度及设计生产能力、服务年限；4.井田开拓；5.准备方式-带区巷道布置；6.采煤方法；7.井下运输；8.矿井提升；9.矿井通风与安全技术；10.矿井基本技术经济指标。
小鱼沟井田位于准格尔煤田东北隅，井田东西长约3.8km，南北宽约3.0 km，面积约11.4km2。井田内主采煤层为6#煤。煤层倾角平均3°，平均厚度12.0 m。井田地质条件较为简单。
矿井工业储量为9233万t，可采储量为8761万t。矿井设计生产能力为1.2Mt/a。矿井服务年限56.16 a。矿井涌水量不大，正常涌水量为20 m3/h，最大涌水量为30 m3/h。矿井相对瓦斯涌出量为1.08m3/t，属低瓦斯矿井。矿井煤尘无爆炸危险性，但煤层易自燃，自然发火等级为I级。
矿井采用斜井单水平开拓。一矿一面，采煤方法为综合机械化放顶煤开采。全矿采用胶带运输机运煤，辅助运输采用无轨胶轮车。矿井通风方式为中央并列式。
矿井年工作日为330 d，日净提升时间16h，工作制度为“三八制”。
专题部分题目是煤矿开采冒落区注浆充填量预计研究。从冒落区注浆充填这种新的充填开采思路出发，通过研究冒落区顶板活动规律和冒落岩块碎胀系数变化规律，提出冒落区注浆量预计方法，为冒落区充填工程提供依据。
翻译部分主要内容为关于锚杆的分析模型，英文题目为：Analytical models for rock bolts。

ABSTRACT
This design includes three parts: the general part, special subject part and translation part.
The general part is a new design of xiaoyugou mine. This design includes ten chapters: 1.An outline of the mine field geology; 2.Boundary and the reserves of mine; 3.The service life and working system of mine; 4.Development engineering of coalfield; 5.The layout of mining area; 6.The method used in coal mining; 7. Transportation of the underground; 8.The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.
Xiaoyugou mine locates at the northeast of zhunge`er Mine area, it has a length of 3.8 km in the east and west direction while a width of 3.0 km in the south and north direction on average. The total area is Approximately 11.4 km2. The main coal seam in the mine is only one, which is the 6# coal seam. The average angle is 3 degree, while the thickness is about 12.0 m. The minefield geological condition is simple.
The proved reserves of the minefield are 92.33 million tons. The recoverable reserves are 87.61 million tons. The designed productive capacity is 1.2 million tons per year. The service life is 56.16 years. The normal flow of the mine is 20 m3 per hour and the max flow of the mine is 30 m3 per hour. The Relative gas discharge quantity is 1.08 m3 per ton. Thus it is Low gaseous mine. The coal dust of the mine has non-explosion hazard. But the coal seam is easily spontaneous combustion. The level of spontaneous combustion is I.
The development of the mine is single level with slope development. The number of the working faces is only one. Comprehensive mechanization puts in the top coal technology is the mining method. Several belt conveyers undertake the job of coal transport in the mine, while the auxiliary transportation system depends on the trackless rubber-tyred car. The ventilation type is centralized juxtapose.
The working days in a year are 330. Everyday it takes 16 hours in lifting the coal. The working system in the mine is “three-eight”.
The title of the special subject part is “The theoretical research on the prediction of grout amount in backfill of collapse zone in coal mining”. A prediction method of grout amount in collapse zone is put forward by studying the regularity of the virgin roof movement and rock crack-expansion in the collapse zone, which provides a basis for the backfill project in collapse zone.
The translated academic paper is about the rock bolts. Its title is “Analytical models for rock bolts”.
Keywords: strip district; comprehensive mechanization puts in the top coal; the trackless rubber-tyred transport; centralized juxtapose ventilation
