综采工作面末采锚网支护技术研究与应用

Research And Application of Bolt-mesh Support in Terminal Mining

综采工作面回采结束前需做出可靠的通风行人及设备回撤通道。通常做设备回撤通道时,在液压支架梁头铺顶网的同时,在支架梁头至煤壁之间沿走向架设圆木梁或钢梁,施工极为复杂,推进度慢且浪费人力、物力。该工作面末采时探索采用锚网支护形式,加快了末采进度,节省了材料、人工。

Reliable ventilation pedestrian and equipment will be withdrawn before the recovery is finished. Usually do device retreat channel, in the hydraulic support beam head roofing network at the same time, in the support beam head between the coal wall along the strike beam or girder erection logs, construction is very complex, promote the degree of slow and waste of manpower and material resources. At the end of the working face, the paper explores the form of anchor net support, speeding up the final production schedule, saving the materials and labor.
