2、0150m3/h，最大涌水量为450m3/h；矿井相对瓦斯涌出量为1.01m3/t，属瓦斯矿井。根据井田地质条件，设计采用双斜井两水平开拓方式，井田采用盘区式布置方式，共划分为四个盘区，辅运大巷、胶运大巷和回风大巷皆为煤层大巷，布置在4-2煤层中。考虑到本矿井为低瓦斯矿井，经过方案比较矿井通风方式采用中央并列式通风，由于工作面推进长度较大，需风量较多在井田开采后期通风较困难，因此在后期在井田两翼设置两个回风斜井，满足井田后期开采需风量。 针对42101工作面进行了采煤工艺设计。该工作面煤层平均厚度为3.2m，平均倾角1，顶板岩性以粉砂岩、细粒砂岩为主，局部为中粒砂岩和泥岩。工作面采用长壁一次采

3、全高综合机械化采煤法。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1.0m，每天8个循环，循环进尺16m，月推进度440m。大巷采用可伸缩式胶带输送机运煤，辅助运输采用无轨胶轮车。专题部分题目为岩巷快速施工技术现状与支护趋势，介绍了矿井岩巷快速施工的现状与支护的趋势，经过查阅大量资料和结合国内外现场应用分析，认为发展快速掘进技术对煤矿经济持续增长有着非常大的意义。翻译部分为Mining Science and Technology中的一篇题目为Discrimination conditions and process of water-resistant key stra

6、 10.The basic economic and technical norms.Liang Shuijing mine is located in YuLin, Shanxi province. Its about 7.9km on the strike and 11.0 km on the dip, with the 69.4 km2 total horizontal area. The minable coal seam is 4-2、5-2 with an average thickness of 2.98 m and an average dip of 0-3. The prov

7、ed reserves of this coal mine are 747.5 Mt and the minable reserves are 2590.72 Mt, with a mine life of 75 a. The normal mine inflow is 100-150 m3/h and the maximum mine inflow is 450 m3/h. The mine gas emission rate is 1.01 m3/t which can be recognized as low gas mine. Based on the geological condi

8、tion of the mine, this design uses a duel-vertical slope double-level development method, and full strip preparation ,which divided into four bands, belt conveyor roadway and return airway are all coal roadways, arranged in the floor rock of 4-2coal seam. Taking into account of the low gas emission,

9、 mine ventilation method use the central paratactic type ventilation, Because working face impelling large length, need to air volume in mining field late more difficult ventilation, therefore in the later in the field set two return air shafts wings, meet later to run mining air volume.The design c

The coal seam average thickness of this working face is 3.2m and the average dip is 1, the immediate roof is mud stone and the main roof is sand stone. The working face applies fully mechanized longwall full-height coal caving method, and
