2、量为7.58 m3/min，为低瓦斯矿井。井田开拓方式为立井单水平上下山式开拓。采用胶带输送机运煤，采用矿车进行辅助运输。矿井通风方式为中央并列式通风。矿井年工作日为330 d，工作制度为“三八”制。一般部分共包括10章：1、矿区概述与地质特征；2、井田境界和储量；3、矿井工作制度、设计生产能力及服务年限；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；10、设计矿井基本技术经济指标。专题部分题目是浅谈我国煤矿底板突水的机理及防治，主要是研究了煤矿底板突水的机理，对防治煤矿底板突水技术做了全面的陈述。翻译部分主要内容是膏体充填在矿井火灾中的

3、应用，英文题目为： Application of Paste Backfill in Underground Coal Fires。关键词：立井；单水平；带区；中央并列式通风ABSTRACTThis design includes three parts: the general part, the special subject part and the translation part. The general part is a new design for Geting mine. Geting mine is located in Geting which comes within

4、the jurisdiction of Jining in Shandong province. It is very convenient to get to the mine in terms of both highway and railway. The length of the coalfield is 3.4 km, the width is about 2.8 km，and the total area is 10.45 km2. The third, the sixteenth and the seveneteenth are the main coal seams, and

5、 the design coal seem (the third) dip angle is 515 degree. The thickness of the mine is about 6.3 m in all. The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 126.20 million tons, and the minable reserves are 93.65 million tons. The designed productive c

6、apacity is 1.2 million tons percent year, and the service life of the mine is 60.03 years. The normal flow of the mine is 99.19 m3 per hour and the max flow of the mine is 248.3 m3 per hour. The relative mine gas gush is 2.98 m3/t and the absolute gush is 7.58 m3/min, so it is a low gas mine. The mi

7、ne is a single level in two shafts to develop. Te central laneway uses Belt Conveyor to transit coal, and trolley wagons are used for accessorial transportation in the roadway. The ventilation mode of this mine is center juxtapose form. The “three-eight” working system is used in the Geting mine. It

8、 produces for 330 days a year. 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 panels; 6. The method used in coal mining;7. Unde

9、rground transportation of the mine; 8. The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10. The basic economic and technical norms of the designed mine.The topic of special subject parts is the Analysis of water inrush in Coal Mining floor. It makes a fully comprehen

10、sive statement of its mechanism and the prevention means.Translation part is aboat paste backfill in underground coal fires. The English title is “Application of Paste Backfill in Underground Coal Fires”.Keywords: Shaft; Single level; Panel； Center juxtapose ventilation目 录一般部分1 矿区概述及井田地质特征1 1.1 矿区概述
