摘　　要：针对回坡底煤矿受厚黄土覆盖层村庄下压煤的影响,通过分析厚黄土覆盖层下伏基岩中存在关键层的条件下,应用概率密度函数法、关键层理论综合分析确定这种特定条件下的条带开采参数。结果表明,这种综合分析确定条带开采参数的方法,具有较高的可靠性,提高了条带开采的采、留宽比,减少了条带工作面搬家次数与掘进工程量是一种经济可行的方法,具有较好的应用价值。In view of the influence of pressure coal under the village of thick loess overburden in the coal mine at the bottom of the slope, the probability density function method is applied under the condition of the existence of the key layer in the bedrock under the thick loess cover. The parameters of strip mining under this special condition are determined by comprehensive analysis of key layer theory. The results show that the method of comprehensive analysis and determination of strip mining parameters has high reliability, improves the ratio of mining and width of strip mining, and reduces the moving times of strip working face and the amount of excavation engineering, which is an economical and feasible method. It has good application value.
