摘要
煤矿井下煤炭回采后形成采空区,顶板会垮落,造成地面塌陷。现在解决的方法是把掘进时产生的矸石不升井,直接运到采空区,用液压支架后面架设的刮板输送机将矸石排放到采空区,由于排放到采空区的矸石是自然堆放,不够密实,而且不能与顶板接顶,达不到防顶板垮落的要求。研制了采空区充填矸石用推矸机,此推矸机可以将矸石推离排放点,并可将矸石堆密实。
After the coal mine coal mining goaf formation, roof caving, causing the ground subsidence.Now the solution is to advance as waste rock, not directly to the mined-out area, with hydraulic support behind erect blowing machine will waste emissions into the mined-out area, due to the discharge of waste rock is a natural stacked to the gob is not solid, and cannot meet the roof and the roof, could not reach the requirements of the roof caving. Was developed for this purpose, the goaf coal gangue filling with push bottles machine, this machine can be pushed the gangue waste rock off a discharge points,and waste rock pile can be compacted.
