Coal seam gas release equipment and method

Abstract

The invention provides coal seam gas release equipment and method, and belongs to the technical field of coal seam gas governing. The coal seam gas release equipment comprises a walking platform, a rotary driving mechanism is arranged on the walking platform, an output shaft of the rotary driving mechanism faces upwards, a main driving wheel is arranged on the output shaft, a supporting frame is arranged on the walking platform, and a maintaining body is transversely arranged on the upper portion of the supporting frame; the main driving wheel is located on one end side of the maintaining body, a driven wheel is rotationally arranged at the other end of the maintaining body, transmission between the main driving wheel and the driven wheel is achieved through an annular circulating knife belt, and the maintaining body is located on the inner side of the annular circulating knife belt and used for supporting and maintaining the annular circulating knife belt. According to the coal seam gas release equipment and method, an existing gas treatment technology of densely-arranged gas extraction drilling holes can be replaced, the treatment cost of coal seam gas is greatly reduced, human input is reduced, mechanical continuous coal seam cutting is adopted, the effective area is increased compared with the drilling holes, the coal seam pressure relief is easier, the coal seam breathability is better, gas can be quickly released, treatment benefits are good. The economic value is high.

Description

technical field [0001] The invention relates to the technical field of coal seam gas control, in particular to a coal seam gas release device and method. Background technique [0002] The comprehensive control of coal mine gas is the top priority of our mine safety production work. Doing a good job in coal mine gas control is an important measure to protect the safety of miners' lives and property and build a harmonious coal mine. The most common method of underground gas control in coal mines in my country is to arrange intensive drilling. The existing coal seam gas extraction methods are mostly through drilling and then introducing negative pressure pipelines to extract the gas existing in the coal seam, thereby reducing gas Concentration, to ensure production safety in the later mining process of coal seam. Due to the densely arranged gas drainage boreholes usually adopted, accompanied by hydraulic flushing, high-pressure fracturing and cavitation and other processes, the...

Problems solved by technology

Due to the densely arranged gas drainage boreholes usually adopted, accompanied by hydraulic flushing, high-pressure fracturing and cavitation and other processes, the process is cumbersome and labor-intensive, requiring a lot of manpower, material and financial resources, resulting in gas control. The cost continues to increase, the demand for labor intensity is greater, and the borehole diameter is limited, the effective area for releasing gas from the coal seam is small, the desorption of gas in the coal seam is slow, and the general drainage cycle is very long
