急倾斜煤层底板巷道布置的安全尺寸研究

Research on The Safe Distance of Floor Roadway Layout in Steeply Inclined Coal Seam

急倾斜煤层开采底板出现卸压带、支承压力带和沿层面的滑移带,通过数值计算分析了底板位移和应力分布规律,及采动影响范围,确定了急倾斜煤层底板巷道布置的安全尺寸。

The paper indicates that different zones such as relievingabutment and slump come into being in floor after the mining in steeply inclined coal seamWith the help of numerical simulation,the paper analyses the floor deformation and the layout of stress distribution and the influenced scope caused by mining with the suggestion of safe distance in floor roadway layout
