The result indicated That the abutment pressure distribution form was similar to that of slicing mining method but its magnitude and affecting range changed.
结果表明,放顶煤采煤法其支承压力分布形式与分层开采法类似,但在量值及影响范围上有增减。
The results show that the abutment pressure distribution on coal pillar is the direct reflection of abutment stress induced by mining on the interfaces of coal seam and immediate roof.
研究结果表明,煤柱上支承压力分布是开采影响岩层相互作用的结果,是开采引起集中应力在煤层与直接顶界面上的直接反映。
Accordingly, the distribution of abutment pressure on the block coal pillar is measured at working face with a steeply inclined seam of the12010 face, NO.
据此原理,实测得到了平煤集团十三矿12010大倾角综放开采工作面走向支承压力和区段煤柱侧向支承压力分布。
Ranges of fractured strata and high stress distribution of abutment pressure are all depend on the degree of mining disturbance on stope strata.
采动围岩破裂范围和支承压力高应力分布范围取决于开采对岩层的扰动程度。
The results of field test indicate that the earth pressure of abutment, different from linear distribution of Coulomb's, acts as parabolic type.
现场测试结果表明,台背土压力大致呈“抛物线型”分布,与库仑土压力理论的线性分布不同。
