摘要
为了优化坚硬顶板条件下巷道支护参数,在1930煤矿37123工作面运输巷掘进期间安设矿压观测仪器,观测巷道矿压显现的特征值,并对观测结果进行分析,掌握了坚硬顶板条件下巷道矿压显现规律及围岩稳定的状况信息,进而判断支护效果,为修改、优化支护参数提供依据,对类似条件下的巷道支护设计具有指导意义。
By mine pressure observation in 37123 roadway during tunneling, the paper analyzed the result of mine pressure observation, obtained the regularity of strata behaviors and the information of surrounding rock stability, determined the supporting effect. The result can provides basis for modifying and optimizing support parameters and can also has guiding significance for roadway support design at similar conditions.
