rock disposal

When the waste stowing technique is used in coal mining,the waste conveyor has some problems which are 1) frequent movement of the conveyor,2) frequent dismounting of its frame,3) continuous shortening of the conveyor belt,and 4) the joint between the discharge end of the conveyor and the position where the wastes fill.

矸石充填采煤对充填巷内矸石运输设备有以下要求:矸石输送机在矸石充填过程中不断外移、机架不断拆除、皮带不断缩短、机尾卸矸点与矸石充填部搭接问题等。

The technical plan of ground temporary transportation system of discharging the waste rock of the auxiliary shaft in Si Ma coal mine was introduced in this paper, which is useful for the design and construction of similar projects.
