摘要
根据云泉15号煤的地质力学条件,通过现场调研、室内试验、数值模拟、理论分析的方法,对掘进期间和采动影响下的围岩变形量、离层量、塑性区的分布规律进行研究,并给出了胶带顺槽的支护参数。
On the basis of geo-mechanics condition of No.15 seam in Yunquan, field investigation, laboratory test, numerical simulation, and theoretical analysis were used to study surrounding rock deformation, separation volume, and distribution law of plastic zone under the influence of mining. The supporting parameters of belt crossheading were also presented.
