摘要
随着综放开采技术的广泛应用,阳泉矿区相关的一些针对性技术问题也越发明显,尤其经历相邻工作面采动影响的综放面沿空侧回采巷矿压显现剧烈,严重制约了综放工作面生产潜力的发挥。阳煤一矿S8102综放工作面回风巷由于受侧向采空区支承压力与采动影响的双重作用,巷道严重变形,局部断面面积不足0.5 m^2,工作面回风巷巷道围岩变形剧烈,工作人员无法顺利通过回风巷,同时也对工作面的通风管理造成严重的不利影响,大大制约了安全高效生产。
With wide application of fully mechanized top coal caving mining technology, Yangquan some specific technical problems are more and more obvious, especially adjacent working face mining influence of fully mechanized caving face along the side of the empty mining roadway pressure severe appearance, severely restricted in fully mechanized top coal caving working face production potential of the play. Yang coal mine S8102 ensemble put working face return airway due to lateral mining goat＂ support pressure and mining influence of the dual role, severe deformation of the roadway, partial cross-section area of less than 0.5 square meters, the working face return airflow roadway surrounding rock of intense deformation, the staff can not pass return air lane, at the same time, also on the working face ventilation management caused serious adverse effects, greatly restricted the safe and efficient production.
