摘要
针对9102综放工作面过空巷支架—围岩稳定性控制难题,运用理论分析、数值模拟及现场实测等研究方法,建立了综放工作面过空巷支承压力变化模型,模拟并分析了空巷距采场不同距离条件下的围岩松动破坏状况,进而制定了端面煤岩体控制措施,较好地保障了工作面过空巷时的支架—围岩稳定性。
In view of 9102 fully mechanized caving face support-surrounding rock stability control problem,the use of theoretical analysis,numerical simulation and field measurement methods,This paper establishes the model of the support pressure change of the gob-side roadway in the fully mechanized caving face,simulates and analyzes the loose and damaged condition of the surrounding rock under different distance from the Stope,and then sets up the control measures of the face coal and rock body,which guarantees the stability of the bracket-surrounding rock in the working.
