1、 毕节学院论文（设计） 第 I 页 摘 要 贵州省毕节市织金县以那镇宝山煤矿， 织金县宝山煤矿位于织金县以那镇南东，其西部边界紧靠以那镇， 至贵州省织金县城 30km，属织金县以那镇所辖。 矿区边界为一不规则的多边形 ， 东界至多吉河，北界至 F1 断层。 井田走向 平均 宽 约 0.92km， 倾向 平均长约 3.1km，面积 2.8085km2。 区内煤炭资源丰富，煤质较好，气候条件适宜。 矿区内交通以公路为主，织金至纳雍、水城的公路 （ S307） 从矿区南部经过，以那镇 至 织金 30km，至 织金火电厂（八步镇） 25km，至 水城 123km， 至 贵阳 215km， 从织金至贵昆

2、线黄桶站的铁路已经开始运营， 交通较为方便 。矿区内矿产丰富，除煤外，还有粘土、石灰岩、铝土质泥岩和铝土岩、稀散元素及煤层气等。粘土可烧制砖、瓦、钻探用泥浆及其它民用；石灰岩广泛分布，当地农民用之作烧石灰原料及建筑石料，当地水泥厂亦用之作原材料。稀散元素：矿区内各稀散元素含量较低，均达不到最低工业品位，不具开采价值。铝土质泥岩和铝土岩：岩层主要位于含煤地层底部，全矿区发育，一般厚度约为 4.5m。岩质不纯，未进行专门采样。 矿井设计开采煤层为井田内的 C8煤层，煤的平均厚度分 别为 1.42m；倾角为 913，平均为 11。矿井按照煤与瓦斯突出、煤层自燃和煤尘具有爆炸性设计。井田的走向长平均为

3、 8.2km，倾斜长平均为 2.8km，井田面积约为 24.9km2；井田内的工业储量约为 3663万吨，可采储量为 3663万 t；矿井的设计年产量为 45万 t/a，设计服务年限为 55a；工作面作业方式采用的是“两班半采煤，半班准备”的工作方式。设计井田内无大的断层和构造，对矿井的正常生产无影响，矿井按高瓦斯矿井设计。井田内采用反斜井单水平上、下山开拓方式，沿井田的倾斜方向，将井田划分成二个阶段，共 18 个区段进行开采。根据井田内无大的断层和构造特点，准备方式为上下山采区准备，采区内为单层准备。 矿井的采煤方法采用的是单一走向长壁后退式采煤法，回采工艺为综合机械化采煤。井下煤炭主要采用

4、皮带运输机运输，材料和矸石等采用矿用电机车和矿车运输。 通风方式采用中央边界抽出式通风，选用矿用隔爆轴流式通风机，采区进风由副斜井进风，主斜井辅助进风。由于本矿井是高瓦斯矿井，所以采用三条上下山，运输上山采用的是独立通风。运输上山采用的是胶带运输，主斜井采用的是“机轨合一”运输方式；轨道上山布置双轨道，车场均为甩车场 毕节学院论文（设计） 第 II 页 Abstract Pick a song to Zhijin county guizhou province bijie city in the township of baoshan mine, zhijin county, baoshan

5、mine located in zhijin county in south east of the town, close to the town, the west boundary to guizhou zhijin county town 30 km, belong to zhijin county to the town. Mining area boundary is an irregular polygon, the east side to the edge, river, the north side to the F1 fault. Means to the average

6、 is about 0.92 km wide, tend to be an average of about 3.1 km long, covers an area of 2.8085 km. The rich coal resources, coal quality is good, suitable climatic conditions. Traffic is given priority to with road in mining area, zhijin to harmony, south shuicheng road (S307) from mining through, to

7、the town to 30 km, zhijin to zhijin coal-fired power plants (town) in eight steps 25 km, and the city 123 km, to guiyang 215 km, from zhijin to the railway line is yellow barrel station began operations, transportation is convenient. Mining in the mine is rich, in addition to coal, clay, limestone,

8、bauxite and bauxitic mudstone, the scattered elements and coal-bed methane, etc. Clay to fired brick, tile, drilling mud and other civilian； Limestone widely distributed, local farmers use burned lime raw materials and building stone, a local cement plant also use raw materials. Scattered elements:

9、the scattered elements content in the mine is low, all can not meet the minimum industrial grade, no commercial value. Bauxitic mudstone and bauxite, rock is mainly located at the base of the coal-bearing strata, the whole mining area development, the general thickness is about 4.5 m. Rock is not pu

10、re, not for sampling. C8 in coal of mining coal seam in coal mine design for the field, the average thickness of coal were 1.42 m； Inclination to 9 13 , an average of 11 . According to the coal and gas outburst mine, the coal seam spontaneous combustion and coal dust explosive design. Tilt field towards an average of 8.2 km long, on average, 2.8 km long, field area of 24.9 km2； Within the field of industrial
