摘要
该设计矿井为鸡西矿业集团城子河煤矿的新井设计,,服务年限63a。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4150m,平均倾斜长3800m,煤层平均倾角11°,属缓倾斜煤层。
本设计矿井采用双立井和集中大巷布置方式。共划分19个带区,其中首带区为1个,达产工作面1个。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,工作面全部为年工综合机械化采煤。作日为330天,采用“三、八”式工作制,工作面长为200m,,每日割六刀。
提升设备为主井采用箕斗提升,副井采用罐笼提升。
由于本人所学知识有限,并缺乏相应的现场经验。因此,本设计中难免会出现一些问题,请各位老师不吝指正。

Abstract
This design mine pit for Jixi mining industry collection round wall sub-river coal mine new shaft design,Design productivity is , service life field altogether division is 2 level mining,in the well field has 4 to be possible to mine coal the well field moves towards long 4150m equally,medium bank long 3800m,coal bed average inclination angle 11°,is the easy gradient coal bed.
This design mine pit uses the double vertical shaft and concentrates the big lane arrangement the well field incline length is big,also is the easy gradient coal bed,as well as factor influences and so on coal bed geological condition,decided in this well field pletely inclines long wall mining coal law mining,Working pletely for synthesis mechanization mining year working day is 330 days,using" three eight"type working system,the work face length is 200m,each knife progress is ,shears six knives every day.
The lift technique primarily well uses the ore basket promotion, the vice-well uses the cage promotion,Because myself study the knowledge to be limited, and lacks the corresponding present s , in this design can have some problems unavoidably, asks fellow teachers the liberal with to point out mistakes.
Key words: Mining coal craft Inclined mining Synthesis mechanization Easy gradient coal bed
绪论
毕业设计是对我们大学四年所学知识的检验,可以考察我们综合运用的能力。通过大学四年的学****我掌握了很多专业知识,这对能够良好的完成毕业设计打下了坚实的基础。我毕业设计的题目是:黑龙江省鸡西市城子河煤矿新井设计。我在毕业实****中收集到了很多城子河煤矿的资料,我的设计基本都是依据这些资料来进行的。由于是新井设计,所以井下所有系统都要由我来完成,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。设计中用到了非常多的专业知识,主
