摘要
本设计为矿井黑龙江省双鸭山矿业集团东荣五矿的新井设计,,。井田平均走向长4km,平均倾斜长3km,煤层平均倾角5°,属近水平煤层。设计的可采煤层共有3层,。
由于井田倾斜长度较大,且为近水平煤层,以及煤层地质条件等因素影响,决定本井田内采用倾斜长壁采煤法和走向长壁采煤法开采,14#煤层工作面为放顶煤,单工作面达产;15#、17#煤层工作面为综合机械化采煤,双工作面达产。设计中采用双立井开拓、单水平划分、集中大巷布置的开拓方式。大巷采用10吨电机车牵引3吨底卸式矿车运输。
采用“四六”工作制,14#煤层工作面长150m,,日进6刀。
关键词:立井开拓、走向长壁采煤法、放顶煤、集中大巷
Abstract
This design is a new mine planning for Dongrong wu Coal Mine Shuangyashan Mining Administration of Heilongjiang Province. Mine planning capacity is . Its service is . The average toward length of the field is 4km,and average skewed length is average inclination of the coal bed is 5°,which is a nearly level coal bed. There are 3 can exploit coal bed in this field, which average thickness is .
As the field is more toward greater length and coal bed is nearly level. And geological condtions Etc. causes impact, decision this field use longer wall coalmining and pit tubs transport one long wall mining on the strike coal mining. 14#coal bed adopts put top coal and one located production; 15#、17#coal bed adopting coal craft as to synthesize the mechanic nation adopt the coal craft and two located production. This mine shaft is applied to double in dined shaft development method and divided one level .The big lane in concentration in adoption arranges, big alley adopt the wiring type generator vehicle of 10t pull the base of 3t unload type mine vehicle transportation,
Adapt “four-six” work situation, 14#coal bed work face is 150 meters length of circle is meters, and times is 6 one day.
Keyword:vertical shaft development longwall coal mining method
Put top coal gathering main roadway
