Title:
COAL-BASED SOLID WASTE TRANSPORTING AND FILLING INTEGRATED MACHINE MINING SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/134336
Kind Code:
A1
Abstract:
A coal-based solid waste transporting and filling integrated machine mining system, comprising a filling hydraulic support (6) and a coal mining machine (7). The filling hydraulic support (6) comprises a hydraulic top plate and a base (601). The hydraulic top plate comprises a front top beam (602) and a rear top beam (603) hingedly connected to each other. A front probe beam (604) is connected to the front end of the front top beam (602), the rear end of the rear top beam (603) is connected to a telescopic sliding rod (1), and a double-operational single-charging non-stop device is fixed on the telescopic sliding rod (1). The method for filling by using the system weakens the influence of underground water pollution on mine production and ecological environment of a mining area, brings good economic benefits and environmental benefits to the mining area, and promotes safe and green mining of coal.
