摘要
为分析研究采场矿压显现规律,运用FLAC3D数值模拟软件,并结合工作面顶底板实际岩性参数建立三维地质模型。通过对采场应力分布规律、回采巷道的应力分布规律及破坏形式进行数值模拟,并结合电磁辐射仪对回采巷道应力分布状态的观测,验证了数值模拟的合理性。
To analyze mine strata pressure behavior law of stope,taking the rock mechanics parameters experiment results of the roof and floor on working face into consideration, the 3D geological model of the coal mining face was established by FLAC^3D. The stress distribution law of the strata, the stress distribution law and destroy forms of rock of mining roadway were analyzed by numerical simulation. The rationality of numerical simulation was verified by field measurement of the stress distribution status of the stope through elec- tromagnetic radiation instrument.
