摘要
为高效开采"三下"压煤,结合天裕煤矿的工程地质条件,通过充采工作面的合理布置,采用采充并行的开采模式,利用膏体充填材料进行空区充填,在110901工作面成功采出煤炭14.6万t,实现经济效益2190万元,且达到了控制地表下沉的目的。
In order to effectively mine"three lower"pressure coal,combined with the engineering geological conditions of Tianyu Coal Mine,through the reasonable layout of the filling working face,adopting the mining and filling parallel mining mode,using paste filling materials to fill the empty area,successfully mined 146000 tons of coal in the 110901 working face,realized the economic benefit of 21.9 million yuan,and achieved the purpose of controlling the surface subsidence.
