摘要
以赵庄矿1306工作面为背景,通过构建力学模型,理论分析得出工作面在断层影响下基本顶保持平衡的条件,数值模拟其超前支承压力的分布变化特征和顶板下沉量,验证了理论分析的正确性。
Based on engineering background of 1306 mining face in Zhaozhuang coal mine, and builded mechanical model, the research has analyed the balanced conditions of main roof under fault influence, showed lead abutment pressure distribution characteristic and roof subsidence quantity by numerical simulation, and validated the theoretical analysis.
