【摘要】：针对我国村庄下厚煤层压煤量巨大的问题,提出进行分层充填开采、覆岩离层及垮落带断裂带注浆充填开采和村庄搬迁新模式开采,以解放村庄下厚煤层。在技术条件可行的前提下,对比分析了不同煤层厚度及不同村庄人口密度时3种开采方法的经济效益。结果表明:3种开采方法的经济利润随煤厚的增加均呈增长趋势,随村庄人口密度的增长均呈下降趋势,分层充填开采的利润增长或下降幅度最小,村庄搬迁方法的利润增长或下降幅度最大。村庄搬迁方法受2种因素的影响巨大,煤层越厚越有利于实施村庄搬迁方法,村庄人口越稀少,村庄搬迁的利润就越高。最后,总结了村庄下厚煤层开采方法选择时应遵循的原则。
[Abstract]:In view of the problem of huge coal pressure in the thick coal seam under the village in our country, it is proposed to carry out stratified filling mining, grouting filling mining in the overburden rock separation zone and fault zone in the collapse zone and new mining mode of village relocation in order to liberate the thick coal seam under the village.On the premise of feasible technical conditions, the economic benefits of three mining methods with different coal seam thickness and different village population density are compared and analyzed.The results showed that the economic profits of the three mining methods showed an increasing trend with the increase of coal thickness, and decreased with the increase of population density in villages, while the profit of stratified filling mining increased or decreased by the smallest extent.The profit growth or decline of the village relocation method is the largest.The method of village relocation is greatly affected by two factors. The thicker the coal seam is, the more favorable it is to implement the method of village relocation. The less the population of the village is, the higher the profit of village relocation is.Finally, the principles to be followed in the selection of mining methods for thick coal seam under village are summarized.
