综放调采工作面过老巷技术

The technology of passing the used roadway in sublevel caving adjusting working face

将1301综放面老巷分为两类:大角度老巷和小角度老巷。针对两类老巷的具体生产实际,采用不同的过老巷方法,取得了良好的经济效益。创新性地使用煤作为充填骨料充填小角度老巷,在节省经济成本的同时,改善了煤质,也为综放工作面过老巷的安全生产积累了丰富的经验。

The used roadways of 1301sublevel caving working face were divided into two types：large angle used roadway and small angle used roadway,according to the concrete production practical of two types used roadways,using different methods to passing them,obtained good economic benefit,innovative use of coal as filling aggregate to filling the small angel used roadway,saving the economic cost while improving the coal quality,and accumulated rich safety production experience of passing used roadways in sublevel caving working face.
