2、，轨道大巷、胶带运输大巷和回风大巷皆为岩层大巷，其中两条布置在12号煤层底板岩层中，一条顶板岩层中。矿井通风方式采用中央并列式通风。针对北一带区采用了带区准备方式，共划分7个分带工作面，并进行了运煤、通风、运料、排矸、供电系统设计。针对12101工作面进行了采煤工艺设计。该工作面煤层平均厚度为4.5m，平均倾角7.6。采煤方法为综合机械化开采。矿井年工作日为330 d，日净提升时间16h，采用“四六制”工作制度，截深0.6m，每天六个循环，循环进尺3.6m，月推进度108m。大巷采用胶带输送机运煤，辅助运输采用架线式电机车牵引1.5t固定箱式矿车运输。专题部分题目为关于工作面炮采高产高效分析与
3、研究，本文采用类比研究、参考有关现场实测数据、结合统计方法、回归理论分析，对炮采工作面的支护系统、块煤率提高、工作面生产系统进行优化做了研究，提出了一些建议和想法。翻译部分是一篇关于电磁辐射在煤矿冲击地压预测中的应用的探讨性论文，英文题目为Calculation of Electromagnetic Radiation Criterion for Rockburst Hazard Forecast in Coal Mines。关键词：立井开拓； 带区布置； 中央并列式通风； 蓄电池电机车运输； ABSTRACTThis design includes three parts: the gene
4、ral part, special subject part and translation part.The general design is about a 1.20 Mt/a new underground mine design of Sima coal mine. Sima coal mine is located in Liupanshui, Guizhou province. The minable coal seam is 12# with an average thickness of 4.5 and an average dip of 7.6. The proved re
5、serves of this coal mine are 113.95 Mt and the minable reserves are 89.34 Mt, with a mine life of 53.2 a. The normal mine inflow is 160 m3/h and the maximum mine inflow is 600 m3/h. The mine gas emission rate is 8.139.93 m3/t which can be recognized as low gas mine. And its have no spontaneous combu
6、stion tendency, and its a coal seam liable to explosion.Based on the geological condition of the mine, this design uses vertical shaft single-level development method, and strip and districts preparation ,which divided into five bands and one districts, and track roadway, belt conveyor roadway and r
7、eturn airway are all coal roadways, arranged in the 3# coal seam. The ventilation type is centralized juxtapose ventilation;The design applies strip preparation against the first band of North One which divided into 7 stirps totally, and conducted coal conveyance, ventilation, gangue conveyance and
8、electricity designing.The design conducted coal mining technology design against the 12101 face. The coal seam average thickness of this working face is 4.5 m and the average dip is 7.6, the immediate roof is mud stone and the main roof is sand stone. Comprehensive mechanization puts in the top coal
9、 technology is the mining method. The working days in a year are 300. Everyday it takes 18 hours in lifting the coal. The working system in the mine is “four-six”and the depth-web is 0.6 m with six working cycles per day, and the advance of a working cycle is 3.6 m and the advance is 108 m per month
10、.Main roadway makes use of belt conveyor to transport coal resource, the xiliary haulage uses the wire laying type electric locomotive to tow the 1.5t fixed box-type mine car transportation.The monographic study is a brief analysis of behavior law of mine pressure of gob-side entry bolting with wire
11、 mesh.This paper has discussed the overlying strata structure of gob-side entry and the law of both surrounding rock stress distribution and surrounding rock deformation.By finishing and analysising the data from worksite, summarized the behavior law of mine pressure of gob-side entry with similar g
12、eological conditions to direct the support design for gob-side entry.The translated part is under a building resembles the paste body backfill to mine the new craft the discussion paper, English topic is Calculation of Electromagnetic Radiation Criterion for Rockburst Hazard Forecast in Coal Mines.K
