Abstract

The invention provides a swing type isolating device for coal mine paste filling exploitation and an isolating method, and belongs to isolating devices and methods for filling mining. One end of a telescopic mechanism of the device is hinged to one end of a lifting mechanism, the other end of the lifting mechanism is connected to a support base, a swing jack is connected between the other end of the telescopic mechanism and the support base, and the tail portion of the support base is provided with a sliding rail. The method comprises the steps that when filling isolation preparation work is conducted, only the swing jack needs to be operated through a hydraulic operating valve so as to adjust the position of an isolating board, a lifting base is used for extruding a bottom sealing strip to seal a bottom board under the action of a lifting jack, a telescopic box is lifted to extrude a top sealing strip to seal a top board under the action of a telescopic jack, a few human assistance measures are used, the isolating device is operated sequentially on the whole working surface, and namely a filling isolating retaining wall is formed on the tail portion of a support. The swing type isolating device and the isolating method have the advantages that during filling mining, isolation of a to-be-filled area is formed rapidly, work of manually putting up an isolating formwork by workers is canceled, manual labor is reduced, and overall filling working efficiency is improved.

Description

Technical field [0001] The invention relates to an isolation device and method for coal filling and mining, in particular to a swing type isolation device and an isolation method for coal mine paste filling and mining. Background technique [0002] Paste filling technology is one of the green mining technology systems for coal mines, and its main purpose is to solve the "three under one up" coal crushing, improve the recovery rate of coal resources, and extend the service life of the mine. [0003] At present, the isolation and plugging of the area to be filled is one of the main difficulties restricting paste filling mining technology. If the isolation and plugging work is carried out by manual methods, it is not only cumbersome to operate, but also labor-intensive, time-consuming and low in efficiency. However, the traditional fully-mechanized mining support is not equipped with an isolation device for sealing filler slurry, and manual construction is also required. The isolatio...
