远距离下保护层开采条件下采动动压区的分析

针对下保护层采动对远距离上覆巷道的动压影响问题,通过离层监测数据、位移监测数据及现场人工观测分析,最后确定出下保护层采动对远距离上覆巷道的动压扰动边界的末端位置、动压高值区的起始位置及动压高值区高峰点的位置,为受动压影响的已掘巷道的超前加强支护提供依据。

Analysis on Dynamic Pressure Area Under Conditions of Long-distance Under-protecting Coal Stratum

Aimming at the problem of the overlying tunnel on the long-range impact of dynamic pressure for mining the under-protective layer,through the abscission layer monitoring data,displacement monitoring data and on-site manual observation and analysis,finally determine mining under the protective layer overlying the tunnel on the long-range dynamic pressure the end of the boundary disturbance location,the dynamic pressure of high value area of the start-ing location and the high value area of the peak dynamic pressure points,and provide a basis to strengthen supporting affected by the impact of dynamic pressure ahead of roadway have been dug to.
