为了研究工作面膏体充填后对底板承压水的防治效果,需对底板破坏深度进行测试.通过单孔恒水压法对底板破坏情况进行测试,得出了采用膏体充填后完整底板最大破坏深度小于5 m,断层影响处底板最大破坏深度小于12 m.而采用垮落法开采时,由经验公式法得出的完整底板最大破坏深度为9.1 m,即采用膏体充填后完整底板的破坏深度下降了46%.该研究可为测定底板破坏深度提供参考依据.
為瞭研究工作麵膏體充填後對底闆承壓水的防治效果,需對底闆破壞深度進行測試.通過單孔恆水壓法對底闆破壞情況進行測試,得齣瞭採用膏體充填後完整底闆最大破壞深度小于5 m,斷層影響處底闆最大破壞深度小于12 m.而採用垮落法開採時,由經驗公式法得齣的完整底闆最大破壞深度為9.1 m,即採用膏體充填後完整底闆的破壞深度下降瞭46%.該研究可為測定底闆破壞深度提供參攷依據.

To study the control effect of confined water after paste filling on the mining face,the depth of floor failure needs to be tested.By the method of water to one drilling at constant pressure,some results were obtained as following: the maximum broken depth of complete floor with paste filling mining is less than 5 m,and the maximum broken depth of floor that was affected by fault is 12 m.However,the maximum broken depth of complete floor is 9.1 m by the empirical formula without paste filling,so the damage degree of complete floor was reduced by 46%.The study are of very important reference vaule on the broken depth of floor.
