Water prevention and control technology of roof bed separation in Cuimu Mine

In order to solve the water inrush disaster form high level roof bed separation in Cuimu Mine,a numeric calculation and water inrush law analysis were applied to the stucly on theroof water inush and water tabe linkage mechanism.,the bed separation developmernt location and overburden water fovw cracking zone developmert eght in cuimu Mine and the bed separation wae disaster prevention and control method was provided.The study results showed that the water table variation ofLuche Formation had a strong relevance with the mine water nrush. The bed separation develogment location and he water fiow cracking zone height showed that a bed separation space and water fling would be developed at the bottom of the Luohe Formation. Based on the previous study water drainage of the bed separaton water with a water detection and drainage borehole in the underground mine was an efe ctive measure to prevent and conrol he ted separation disaser The prevention and control technology could have a max water infow controlled below 3o0 n3 h uring the mining perod fN0.2103 ceal minin fave and asocoud proide te countermeasures to the design on the oof bed separation water preverntion and conrolofth full -mechanized top cal caving miming n West China Jurossecodl rsources.
