Problems solved by technology

Since the coal seam after coalbed methane mining is generally a coal seam after fracturing, when coal mining is performed directly with an ordinary coal cutter for coal mining, due to the release of fracturing cracks and the impact of subsequent mining, often This makes the coal seam cutting prone to the problem of knife jamming. Moreover, the coal of this mining method often has problems of unequal particle size, and such coal blocks of unequal size will have an impact on transportation and subsequent application, which is not conducive to automatic transportation. And subsequent processing, affecting mining efficiency

Abstract

The invention discloses a coal mining device based on the coordinated safe and efficient mining of coal and coalbed methane, which can realize automatic mining of coal, and at the same time of mining by cutting coal, it can classify the size of coal blocks, and after classification The coal blocks are transported intermittently, which is convenient for the classified transport of coal blocks of different sizes, without adding conveying equipment, improving the utilization rate of equipment, and improving the efficiency of coal mining; the cutting coal mining mechanism of the present invention, by setting the angle bracket assembly, The angle bracket assembly is configured so that the cutting knife can vibrate slightly in the direction of cutting depth during cutting, which can effectively improve the efficiency of coal mining and prevent problems such as knife jamming and clamping. Through slight oscillation, it can The coal cuttings can be discharged conveniently, the coal cutting gap can be increased, and the falling of coal blocks is convenient. The invention has simple structure, convenient use, and can realize fast coal mining operation.

Description

technical field [0001] The invention specifically relates to a coal mining device based on the cooperative mining of coal and coalbed methane, which is safe and efficient, and relates to the related field of coal mining. Background technique [0002] At present, for coal mining, in order to realize the mining of coalbed methane at the same time and reduce the dangerous problems such as gas during coal mining, in order to improve the efficiency of coal mining, the coal seam is mined at the same time or later. There are more and more applications. Since the coal seam after CBM mining is generally the coal seam after fracturing, when the coal is mined, the ordinary coal cutter is directly used for coal cutting mining, due to the release of fracturing fissures and the influence of subsequent mining, often This makes the problem of knife sticking easy when cutting the coal seam. Moreover, the coal in this mining method often has the problem of unequal particle size, and this une...
