| 摘 要： | 以王庄煤业3043大采高工作面矿压观测与矿山压力显现的规律分析为例,通过现场实测数据对液压支架的适应性及对顺槽巷道超前支护稳定性进行了分析,得出了工作面一侧为实体煤及一侧采空区时,工作面超前支撑压力的影响范围和压力变化曲线,可为大采高巷道支护与支架选型提供科学依据.

| Abstract: | Taking an example of pressure observation and strata behavior study of 3043 large-mining-height working face in Wangzhuang Coal Co.,field data were used to study the adaptability of hydraulic support and lead support stability in crossheading roadways to conclude impact range and variation curve of lead support pressure,when one side of working face was coal and the other side was goaf.The study can provide a scientific foundation for support selection in the large-mining-height roadways. |
