针对综放沿空动压巷道围岩稳定性进行了模拟研究,分析了沿空动压巷道围岩受邻近工作面回采全过程下位移场、应力场及塑性区的分布特征和变化规律。研究结果对制定沿空动压巷道围岩的控制对策起到了指导作用。
Aiming at the stability of surrounding rock of roadway with pressure and pressure in fully mechanized top coal caving, the distribution and change law of displacement field, stress field and plasticity zone are analyzed under the whole mining process of the adjacent rock face. The research results play a guiding role in making control measures for the surrounding rock of the roadway with dynamic pressure and pressure.
