摘要
,共有4层设计可采煤层,平均总厚度为8m。,服务年限为57a。划分二个水平开采。,,°,属于缓倾斜煤层。
本设计矿井采用双立井的开拓方式,集中大巷布置方式。共划分8个带区,其中首带区为二个,达产工作面一个。本设计带区为东一带区,大巷装车式下部车场,综合机械化采煤。年工作日为330d,采用“四、六”式工作制,工作面长为200m,,每日割九刀。
提升设备为主井采用箕斗提升,副井采用罐笼提升。
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。
关键词可采储量采煤工艺倾斜开采联合开采联合开拓
Abstract
The task of this design is to construct a tons new shaft for Dayan of the four mine has four minable Coal Seam,and its average thickness is 8 field of minable capacity tons. It can adapt for 57ars, and is divided into one levels. Average alignment in farmland in well lengthways average slant lengthways average rake angle in coal seam °, belong to the the slant the coal seam.
This mine shaft is applied to double indined shaft development method; Layout of gathing gallergand mining district eross heading; The well farmland turns to is divided into totally 8 adopt the synthesis mechanization mining coal and one worked faces. This worked face is east worked face, words 330 days every year. Adapt “four-six” work situation, work face is 200ters length of circle is , and times is nine one day.
Because the well farmland slant length is bigger, and incline the coal seam for the , and coal seam geology c. factor effects, deciding this well farmland inside plete adoption slant.
Key words Recoverable reserves The technology of coal mining Adoption slant Unites to mine Unites to expand
绪论
毕业设计开始了,大学的学习也相应的结束了。毕业设计就是对大学四年的知识的一次系统的总结。在设计中,从开拓的选择到井筒的布置,从采煤方法的确定到巷道断面的设计,都有着我的合理的选择.
。大雁地形地势平坦,煤层地质构造简单,煤层赋存浅。在井田范围内只有一个小断层F8,此断层平距0~16m,断距0~20m。,,采用双立井开拓方式,倾斜长壁采煤法进行采煤。
我国煤炭资源丰富,储量和产量均居世界前列。近年来随着国民经济的发展和综合国力的提高,石油、天然气、水力、核电等其他能源有了较大发展,但是煤炭仍然是我国的主要能源,预计在今后相当长的一段时期内这种状况不会有根本性改变。进入21世纪,要求我国煤炭工业深化改革,尽快摆脱粗放经营的旧模式,步入低投入、高产出、高效益的良性循环轨道。
