煤矿充填开采充填体承载能力影响因素研究

 煤矿充填开采时充填体的承载能力十分重要。根据影响充填体承载能力的因素，建立了充填体承载能力的模型，运用数值模拟软件FLAC进行模拟计算，得出了充填体承载能力的大小随着充填体宽度和强度增大而增大，随着充填体高度和采深的增加而减小，为以后充填体的参数选择提供理论支持。

Study on the influence factors of the bearing capacity of Coal mining with Backfilling

The bearing capacity of the bearing body is important in the process of coal mining backfilling. According to affecting filling body bearing capacity of factors, established the model, using the numerical simulation software FLAC, it is concluded that the bearing capacity of the bearing body is increasing as filling width and strength increasing and decreasing as filling height and mining depth increasing, which would have provided theoretical support to parameter selection of filling body.
