2、田开拓方式为立井两水平上下山开拓，二水平采用暗斜井延深。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。中央采区采用了采区准备方式，共划分为三个工作面，并进行了运煤、通风、运料、排矸、供电系统设计。针对8501工作面进行了采煤工艺设计。该工作面煤层平均厚度为10.0 m，平均倾角28。工作面采用综采放顶煤采煤法。采用双滚筒采煤机割煤，往返一次割两刀。采用“三八制”工作制度，截深0.6 m，每天2个循环，循环进尺1.2 m，月推进度72 m。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

3、式采区巷道布置；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。专题部分题目是矿井热害及其防治技术研究，主要是介绍了矿井热害的现状就其有效的防治技术的研究。翻译部分主要内容是关于自传式旁压仪在波斯肯纳粘土中的渗透性测量，英文题目为：Self-boring pressuremeter permeability measurements in Bothkennar clay。关键词：涡北煤矿新型矿井 立井两水平 上山 中央并列式 综合机械化放顶煤开采 热害ABSTRACTThis design includes three parts: the ge

4、neral part, the special subject part and the translation part. The general part is about a 1.80 Mt/a new design for Gobei mine. Gobei mine is located in Bozhou City, Anhui province. the traffic is convenient.The length of the coalfield is 6km,the width is about 3.2 km，and the total area is 18 km2.Th

5、e 8th is the main coal seams with average dip of 18.The thickness of the mine is about 10.0 m in all. The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 192.92 million tons and the minable reserves are 117.42 million tons. The designed productive capacit

6、y is 1.8 million tons percent year, and the service life of the mine is 50.1 years. The normal flow of the mine is 282 m3 per hour and the max flow of the mine is 395 m3 per hour. The relative mine gas gush is 6.77 m3/t and the absolute gush is 29 m3/min, so it is a low gas mine. The mine is a verti

7、cal shaft development with two mining levels and the extension of blind inclined shaft. 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 design applies distr

8、ict preparation against the first district of centra One which divided into three longwall faces totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity designing.The design conducted coal mining technology design against the 8001 face. The coal seam average thickness

9、of this longwall face is 10.0 m and the average dip is 28, The face applies fully-mechanized coal caving mining method, and uses double drum shearer cutting coal which cuts twice each working cycle. “Three-Eight” working system has been used in this design and the depth-web is 0.6 m with two working

10、 cycles per day, and the advance of a working cycle is 1.2 m. So the advance is 72 m per month.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. min

11、ing district preparation; 6. The method used in coal mining; 7. Underground 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 Mine Hea
