芙蓉煤矿采用平峒开拓,沿煤层布置上山,走向长壁后退式开采,边界抽出式通风,煤层易自然发火,发火期6～12个月,属高沼气矿井。上平峒自1970年投产以来,井下漏风造成回采工作面和老塘发火达14次,我们采用调节风压、控制风量、减少漏风措施,达到了以风防火、以风灭火的目的。现举例分析如下。 Furong Coal Mine Pingdingshan exploit, up the mountain along the coal seam, toward the long-wall backward mining, the border out of ventilation, easy spontaneous combustion of coal, firing period of 6 to 12 months, is a high biogas mine. Since it was put into operation in 1970, due to the downhole wind leakage, the working face and the Laotang coalface have fueled 14 times. We adopted the measures of adjusting the air pressure, controlling the air volume and reducing the air leakage to achieve the goal of using wind to prevent fire and wind to extinguish fire. The following is an example analysis.
