尾砂水力充填脱水及空区密闭试验研究

Experimental study on dewatering and sealing of minedout area in hydraulic filling with tails

介绍了在采空区充填时采用木结构密闭墙、负压脱水和渗滤管过滤材料清理系统等技术，加快了脱水速度，减小了充填材料对密闭墙的压力，为确保连续充填创造了条件。

This paper introduces the techniques of sealed stopping in wood structure,dewatering by negative presure and cleaning system of filtering with percolation pipe,accelerating dewatering of filling material;minifying the pressure of filling material to sealed stopping and creating the condition of filling contiuously.
