摘要
该设计矿井为鸡西市成子河矿的矿井设计,,服务年限56a。井田共划分为2个水平开采,井田内有4层可采煤层。井田平均走向长3750m,平均倾斜长3300m,煤层平均倾角11°,属缓倾斜煤层。
城子河矿位于鸡西市鸡西火车站东北约5公里。其地理坐标为东经北纬。矿内有运煤专用铁路与国铁林密线西鸡西车站相连,,。此外上有公路通往鸡西、勃利、哈达、四海店等地,交通十分方便。
由于井田倾斜长度较大,且为缓倾斜煤层,以及煤层地质条件等因素影响,决定本井田内全部采用倾斜长壁采煤法开采。工作面全部为综合机械化采煤。

Abstract
Change to design mineral well as the mineral well that chicken west City almond spend the mineral design, designing production ability as Mts/ a, service time limit 70 well farmland turns to is divided into totally 2 adopt the zone mines, the well farmland inside has 5 lamellas can adopt the coal alignment in farmland in well lengthways 4500 ms, average slant lengthways4300 ms, average rake angle in coal seam 11 °, belong to the the slant the coal seam.
Well farm land chicken east County reaches the town is inshore with chicken west City almond flower is horizontal in highway in national defense in city this well farmland, horizontal interleave in inshore big driveway, all can farmland south side contain the strand of to state-owned railroad in eastern and red and male line, north side in farmland in well contain city son river carries to the positive positive mineral well coal appropriation well farmland is apart from the chicken west station kilometer, reach the river station to the 12 kilometer, the transportation is more convenient.
Because the well farmland slant length is bigger, and incline the coal seam for the , and coal seam geology condition etc. factor effec
ts, deciding this well farmland inside plete adoption slant 。
绪论
通过大学四年的学****我掌握了很多专业知识,为了能更好的巩固和运用这些知识,借毕业设计这个机会我做了黑龙江省双鸭山市新安矿的新井设计,而且我在毕业实****中也收集到了很多新安矿的资料。本设计主要是关于新矿井的建设,其中包括开拓方式、采煤工艺、支护方式、设备选型以及矿井的各个系统。本设计包括通风安全方面、采煤工艺方面、岩石力学方面以及CAD制图方面的知识。采矿方面的知识更新很慢,本设计采用了一种创新模式,这是一个新的方案,主要是针对小倾角煤层群的开采方法,本方法采用反倾向的巷道布置,不需要布置上下山,因此,可以节省很多开采费用,也更利于矿井的生产和管理。本设计主要是通过绘制矿井的各种图纸来进行矿井的优化设计,这其中文字部分包括大量的方案比较,以便使设计更加合理。在设计时,需要对矿井的地质情况、煤层的受力
