摘要
针对大面积冒顶不仅影响着施工巷道掘进效率,而且加大了巷道掘进难度,很容易发生重大煤矿顶板事故,对塔山扩区2301巷冒顶区域采取了合理有效的安全支护措施,实践证明采取措施后提高了顶板稳定性,取得了显著成效。
Aiming at the large-area roof fall which will not only influence the drilling efficiency of construction roadway, but also increase the drilling difficulty and cause serious roof accident, the author proposes the reasonable and effective safety support measure in roof-fall area of 2301 roadway, which has been proved to Improve the roof stability effectively.
