后退式分层采煤机械设备开采参数的计算

Calculation of Mining Parameters of Backward Layered Coal Mining Machinery and Equipment

以1413A工作面后退式分层走向长壁综合机械化采煤方法为工程背景,在搜集大量的文献资料及煤矿现场调研基础上,针对后退式分层走向长壁综合机械化采煤现场条件,综合考虑了工作面布置方式、巷道掘进支护、采煤、运煤及支护方式,确定选择了后退式分层走向长壁综合机械化采煤技参数,确定设备选型。

Based on the engineering background of 1413 A working face backward delamination to long wall comprehensive mechanized coal mining,on the basis of collecting a large number of literature and field investigation,aiming at the site conditions of backward delamination and longwall comprehensive mechanized coal mining,the layout of working face,roadway excavation support,coal mining,coal transportation and support mode are comprehensively considered.The technical parameters of backward delamination and longwall comprehensive mechanized coal mining are determined,and the equipment selection is determined.
