A side-side coal recovery process for open-pit continuous excavation working face

Abstract

The invention belongs to the technical field of application of coal mining equipment and coal mining methods and particularly relates to a recovery process for side coal on an open continuous excavation working face. The recovery process comprises the steps of mining cavern arrangement, arrangement and mounting of mining, transporting and supporting equipment and mining, specifically, a track traveling cavern opening protection ceiling is arranged outside a mining cavern opening, and after a track traveling coal mining machine conducts hole-cutting construction at the mining cavern opening, asupporting steel shed is erected in the mining cavern opening; the track traveling coal mining machine pulls transporting units to continue to enter a cavern for coal mining, and after the coal miningdepth reaches the length of one transporting unit each time, the another transporting unit is additionally arranged; and after depth mining of the current cavern is finished, the track traveling coalmining machine, the transporting units and the support steel shed are all removed out of the cavern and transferred to the next mining cavern opening, the steps are repeated to continue to recover coal, and a mining-transporting-supporting-remote control combined production mode is formed. Through the coal mining process, the mining recovery problem of the open side coal is effectively solved, the equipment is arranged compactly and continuously, safety, stability and reliability are achieved, the mining efficiency is high, and the recovery process for the side coal on the open continuous excavation working face is quite ideal.

Description

technical field [0001] The invention belongs to the technical field of the application of coal mining equipment and coal mining methods, and in particular relates to a side-side coal recovery process of an open-pit continuous excavation working face. Background technique [0002] After the mining of the open-pit coal mine is completed, the coal resources of the open-pit sidewall pressure formed at present have reached tens of millions of tons, and it is increasing year by year. Overlapping will lead to difficulty in recovery or loss of recovery value, so the recovery of side pressure coal is urgent. Open-pit side coal recovery is an extension of open-pit coal mine recovery and production of coal by underground methods. However, the side-side coal mining technology that can be remotely controlled by ordinary shearers and belt conveyors is not yet perfect, and cannot fully adapt to side-side mining. Moreover, the transportation system supporting facilities and hole protection...

Open-pit side coal recovery is an extension of open-pit coal mine recovery and production of coal by underground methods. However, the side-side coal mining technology that can be remotely controlled by ordinary shearers and belt conveyors is not yet perfect, and cannot fully adapt to side-side mining. Moreover, the transportation system supporting facilities and hole protection are simple, which restricts the overall production efficiency and poses safety hazards
