摘要
缓倾斜中厚矿体因其特有的地质和力学特点,为煤矿开采带来了一系列挑战,其中矿岩的软破效应是 1 种非线性力学行为,对煤层的稳定性和开采具有一定的影响.传统的开采方法在该地质环境下效果较差,需要重新审视和研发新的开采策略.因此,深入研究了缓倾斜中厚矿体的特性,并对不同的开采方法进行了详细的分析,以期为煤矿开采提供更加合理和高效的开采建议.
Abstract
Due to its unique geological and mechanical characteristics,the gently inclined medium-thick ore body brings a series of challenges to coal mining,among which the soft fracture effect of mineral rock is a nonlinear mechanical behavior,it has certain influence on the stability and mining of coal seam.Traditional mining methods are not effective in this geological environment,so it is necessary to re-examine and develop new mining strategies.Therefore,the characteristics of gently inclined medium-thick ore body were deeply studied,and different mining methods were analyzed in detail,in order to provide more reasonable and efficient mining suggestions for coal mining.
