Slotting equipment for coal seam gas control

Abstract

The invention provides slotting equipment for coal seam gas treatment, and belongs to the technical field of coal seam gas treatment, the slotting equipment comprises two slotting main machines which work synchronously and coordinately, the two slotting main machines are arranged in roadways on the two sides of a coal seam respectively, and the two slotting main machines are in transmission connection through an annular cutting rope; the slotting main machine comprises a self-walking platform, a power module, a speed reducer, a gear reverser and a main driving line wheel are arranged on the upper portion of the self-walking platform, and the power module transmits power to the gear reverser through the speed reducer. According to the invention, the annular cutting rope which circularly moves is adopted as cutting force, and is combined with feeding force provided by the two slotting main machines which synchronously and coordinately work, so that one or two slots can be transversely cut in the coal seam, and traditional high-density drilling is replaced, so that the labor intensity is greatly reduced, the cost is saved, an anti-reflection area formed by the slots is larger, and the anti-reflection effect is better. And gas desorption is facilitated, so that the gas extraction efficiency is greatly improved.

Description

Technical field [0001] The present invention relates to the field of coalbed methane treatment technology, specifically to a kind of kerfing equipment for coalbed methane treatment. Background [0002] Coal mines need to release and extract the gas in the coal seam before mining, otherwise there is a great safety hazard. At present, the simplest and most effective way to implement gas treatment is to increase the area of pumped gas through high-density drilling, but this gas treatment method requires intensive drilling, and there are problems of high labor intensity, high labor and low efficiency. Contents of the Invention [0003] In view of this, the present invention provides a kind of beaking equipment for coalbed methane treatment, using a circular motion of the circular cutting cable as a cutting force, and combined with the feed force provided by the two simultaneous and coordinated work of the slit host, it is possible to cut one or two cut seams horizontally in the coal...
