在突出矿井突出煤层石门揭煤过程中,由于穿越石门和煤门的距离长,工程周期长,揭煤时诱发突出危险的可能性大,而且在放炮揭煤时很难一次揭穿煤层,极易发生延期突出,一直以来是煤矿防突技术难题,给生命和财产带来巨大损失。陶二煤矿利用石门反向揭煤技术安全快速揭开高突煤层,具有抽放时间短、节省岩石钻孔工程量等技术优点,为煤与瓦斯突出矿井石门揭煤探索出一条安全、快速的技术途径。
在突齣礦井突齣煤層石門揭煤過程中,由于穿越石門和煤門的距離長,工程週期長,揭煤時誘髮突齣危險的可能性大,而且在放砲揭煤時很難一次揭穿煤層,極易髮生延期突齣,一直以來是煤礦防突技術難題,給生命和財產帶來巨大損失。陶二煤礦利用石門反嚮揭煤技術安全快速揭開高突煤層,具有抽放時間短、節省巖石鑽孔工程量等技術優點,為煤與瓦斯突齣礦井石門揭煤探索齣一條安全、快速的技術途徑。

In the outburst coal seam cross-cut cropping out coal of outburst coal mine process, due to the long distance of cross-cut and coal-cut and long project cycle, the possibility of outburst risk is large, the coal seam is difficult to debunking for once when shooting, and extension outburst is easily appeared, which has always been coal mine outburst prevention technology problems, brought huge loss to life and property. Taoer coal mine uses reversed cross-cut cropping out coal technology to quickly uncover the high outburst coal seam, which has short drainage time, saving rock drilling and other characteristics, explores a safe, rapid technological means for coal and gas outburst cross-cut.
