摘要
针对易自燃煤层在回采过程中经过地质构造带时易发生煤自燃的现象,分析了自燃原因,并采用高位钻孔注水的方法针对性地治理了采空区浮煤自燃。通过在3205工作面回采过程中的实际应用证明,该方法实施了15 d就有效地解决了采空区浮煤的自然发火隐患,并对降尘起到了很好的效果。
Aiming at solve problems of spontaneous coal combustion when recovering comes into the inflammable coal seam through the geological tectonic zones, a fire extinguishing application by using high position drilling water injection was presented. The 3205 working face test proved the efficiency of the technique, only 15 days were taken to unseal the coal mine, which can effectively solve the hidden dangers of spontaneous coal combustion in the goaf, and have a good effect on dedusting.
