摘要
为解决阳煤一矿回采工作面动压巷道影响工作面高效生产的技术难题,通过在8304工作面使用超强矿用无机材料对三角煤进行超前注浆加固,实现了对顶板的有效管控,维护了三角煤区域的稳定性,改善了动压巷道状况,为工作面高效生产创造了条件.
In order to solve the technical problem of dynamic pressure roadway affecting the efficient production of mining face, the effective control of roof is realized by using super strong mineral inorganic material in 8304 working face. The stability of triangle coal area is maintained, the condition of dynamic pressure roadway is improved, and the condition of high efficiency production is created.
