| 摘 要： | 通过对龙口北皂矿H2101海域工作面矿区煤层底板矿物成分分析、岩样的膨胀性试验以及对巷道底板含水状态和围岩蠕变的实测,得到有关软岩巷道的围岩岩性参数和实际蠕变规律。运用湿度应力场理论的数学模型方法对软岩巷道的遇水软化和膨胀特性进行了分析,根据湿度应力场理论推导出膨胀软岩本构方程,在实际软岩巷道围岩稳定性控制中得到了应用。

| Abstract: | he lithologic parameters of rocks surrounding the roadway and their actual creep regularity were obtained through the analysis on the mineral compositions in seam floor, the test on the swelling property of rock samples and the actual measurement of water-bearing state in roadway floor and the creep of surrounding rock in H2101 working face under the sea area in Longkou Coal Mine. The softening and swelling properties of soft rock roadway in contact with water were analyzed by using the mathematic model of humidity stress field theory and the constitutive model of swelling soft rock was derived according to the humidity stress field theory. These research results have found application in the control of surrounding rock stability of the soft rock roadway. |
