摘要
提出通过超前注浆提升松软煤体稳定、强化采面管理及适当提高采面推进速度降低矿压影响。现场应用后,采面在松软煤层带期间未出现煤壁片帮、冒顶等问题,实现了采面安全高效回采。
Advance grouting is proposed to improve the stability of soft coal,strengthen the management of mining face and appropriately improve the advancing speed of mining face to reduce the influence of ground pressure.After field application,there are no problems such as coal wall caving and roof fall in the soft coal seam zone,and the safe and efficient mining of the mining face is realized.
