Novel deslagging system and method on deep shaft full-face heading machine

The invention provides a novel slag discharging system on a deep shaft full-face heading machine. The novel slag discharging system comprises a first-stage bucket elevator slag discharging unit, an underground loading unit, a second-stage bucket elevator slag discharging unit, a ground unloading unit and a control unit. The primary bucket elevator deslagging unit comprises a heading machine and a bucket elevator; and the bucket elevator discharges the rock slag to an underground loading unit. The underground loading unit comprises a surge bin and a quantitative bin; the surge bin receives rock slag, and the quantitative bin loads the rock slag to the secondary elevator slag discharging unit. The secondary elevator deslagging unit comprises a skip bucket and an elevator; the skip bucket receives the rock slag which is lifted to a wellhead by the elevator. The ground unloading unit comprises an external power opening and closing device and the like; the rock slag is unloaded to a pit through the external power
