摘要
杏花煤矿开采30#层为高瓦斯煤层,通过采用顶板高抽巷等瓦斯抽放技术,有效治理本层及邻近层瓦斯,有效地解决了采煤工作面上隅角及回风瓦斯超限问题,实现了矿井的安全生产和高产高效。
No.30^# coal seam mined in Xinghua Coal Mine is a high gas coal seam. By using the gas drainage teehnology with the roof high pumping lane, the gas of native layer and near layer is effectively managed. The gas transmit problem in the upper corner and return airway at the coal face is solved, the mine safety production, high yield and high effieiency are realized.
