Outburst prevention device for coal mine underground coal roadway tunneling drilling construction

Abstract

The invention discloses an outburst prevention device for coal mine underground coal roadway tunneling drilling construction. The device comprises a first box body, a second box body, a bearing plate,a rotating plate and an air suction hopper, wherein the first box body is fixedly connected with the second box body, sliding wheels are arranged at the bottom of the first box body and the bottom ofthe second box body correspondingly, a supporting rod is vertically arranged in the middle of the interior of the second box body, one end of the supporting rod is fixedly connected with the inner wall of the second box body, the other end of the supporting rod is fixedly connected with the middle of a rotary disc, the rotary disc is rotationally arranged, the upper surface of the rotary disc isfixedly connected with the bottom end surface of a hydraulic cylinder, a telescopic end of the hydraulic cylinder penetrates through the upper surface of the second box body to extend to the outside and is fixedly connected with the bottom end surface of the bearing plate, a telescopic air cylinders and a swing rod are symmetrically arranged on the upper surface of the bearing plate, the two sections of swing rods are included, and one ends of the swing rods are hinged to each other. The outburst prevention device for coal mine underground coal roadway tunneling drilling construction is reasonable in structure, effectively improves the construction safety of a mine, and can be widely popularized.

Description

technical field [0001] The invention belongs to the technical field of coal mines, and in particular relates to an outburst prevention device for excavation and drilling of underground coal roadways in coal mines. Background technique [0002] A mine is a general term for the wells, chambers, equipment, ground buildings and structures that form the underground coal mine production system. Occasionally, the inclined shafts, shafts, and flat tunnels in the underground development of mines are also called mines. The determination of the size of the mine field, mine production capacity and service life of each mine is one of the key issues that must be solved in the design of the mine itself. For mines with large wells, the investment in fixed assets is large, and the investment per ton of coal (production per ton of coal) capacity investment) is high, in order to exert the effect of investment, the service life of the mine should be longer. From the perspective of ensuring ba...

Problems solved by technology

[0003] During the mining process of coal mines, there will be a phenomenon of gas gushing out, which is caused by the pressure in the medium. If measures are not taken in advance, accidents will occur. There is an urgent need for a coal mine underground coal roadway tunneling and drilling Construction anti-shock device to meet the needs of use
