摘要
Abstract
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.关键词
