【摘要】:为了探求综放开采条件下导水裂隙带发育高度与采厚的关系,采用数值模拟方法对综放开采导水裂隙带发育高度进行了模拟计算,通过与工程实测数据的对比分析,获得本区综放开采导水裂隙带裂高采厚比平均值为16.76,综放开采产生的导水裂隙带发育高度比分层开采的大,为相似区域内、相同条件下导水裂隙带发育高度预计提供了参考。
[Abstract]:In order to find out the relationship between the development height of water-conducting fissure zone and mining thickness under fully mechanized caving mining condition, the development height of water-conducting fissure zone in fully mechanized caving mining is simulated and calculated by using numerical simulation method. It is obtained that the average value of the ratio of high mining thickness to high mining thickness of the fissure zone of water conduction in fully mechanized caving mining area is 16.76, and the development height of the fissure zone of water conduction produced by fully mechanized caving mining is larger than that of stratified mining, which is in the similar area. The prediction of the height of the fracture zone under the same conditions provides a reference.
