摘要
针对一般条件下的采空区,依据直接顶冒落和基本顶沉降的状况,将其划分为3个区域。通过现场观测得出的冒高经验公式和顶板冒落的碎胀值,在数值模拟中,作相应转化,划分出相应的区域,不同的区域采用不同的处理方式,使采空区更加接近现场条件。
Based on the condition of immediate roof falling and main roof settlement, directed toward general condition, the gob is divided into three areas. In numerical simulation, corresponding division is done according to empirical equation of falling high and the value of crack and swelling. Differente processing modes are adopted in differente areas so that the gob is closer to real condition.
