摘要
研究分析了王庄煤业3501大采高综采工作面顶板破碎影响快速"收尾"问题,提出了适合该矿快速收尾的技术,对于不稳定顶板的压力控制,只有加大撤架通道内的支护强度,才是可靠途径。
The paper studies the influence of broken roof on the ending on No.3507 large-mining-height fully-mechanized mining face and proposes some suitable rapid ending technology for the mine. In terms of stress control of unstable roof, it is the only reliable approach to increase the supporting intensity in the gateways where supports are removed .
