晋华宫矿半煤岩巷快速掘进技术及管理

Rapid Excavation Technology and Management on Half Coal Seam Roadway in Jinhuagong Colliery

针对半煤岩巷掘进速度慢的问题,以晋华宫矿7-3#煤层5704巷为研究对象,采用了"以人为本,动态设计,科学调控"的指导思想,提高了工人的积极性,减轻了工人的劳动强度,使钻进、出渣、支护等设备配套,工序严谨,提高了掘进速度,取得了平均月进尺339m,最大月进尺368m的掘进速度,实现了中厚煤层半煤岩巷的快速掘进。

Aiming at the problem of slow excavation in half coal seam roadway and taking 5704 roadway in 7--3 # layer of J inhuagong Colliery as research subject, the author proposes adhering to the guiding principle of ＂people --oriented, dynamic design, scientific regulation＂ for construction, which increases workers＂ motivation, re- duces the labor intensity with coordinative drilling, mucking, and support equipments and rigorous process, im- proves the driving speed with 339m average monthly footage and 368m maximum monthly footage, and achieves rapid excavation of half coal seam roadway with medium--thickness seam.
