Abstract

The invention provides a coal seam drilling coal-gas-water separating, conveying and containing device, comprising a dynamical-static combined type sealing and rapid mounting collector, a coal-gas separating conveyor, and a coal-water separator, wherein the collector is connected with the tail end of a hole protection tube, and is provided with a gas pump drainage opening, a coal and gas conveying opening and a drilling opening; a sealing structure sealed with a drilling rod is arranged at the drilling opening; the coal-gas separating conveyor is provided with a buffer separator, a coal-water conveying system and a supporting system; the buffer separator is provided with a gas pump drainage opening and an overload discharging door; the coal-water conveying system is a sealed system, and is communicated with the buffer separator through the overload discharging door; an output end of the coal-water conveying system is connected with the coal-water separator through a connection pipe; and the coal-water separator comprises a dewatering system, a conveying system and a supporting system. With the adoption of the coal seam drilling coal-gas-water separating, conveying and containing device provided by the invention, not only can coal, gas and water sprayed out in a drilling process of a de-dusting coal seam be effectively separated, contained and conveyed, so that the efficiency of using drilling on the coal seam can be improved; but also the stronger safe protection can be provided, and the coal seam can be safely drilled.

Description

technical field [0001] The invention relates to a device for preliminary separation of coal, gas and water and inductive transportation of jets from hydraulic mining in the process of hydraulic mining of thin and soft coal seams. Background technique [0002] For thin and soft coal seams, hydraulic mining is an economical, safe and reliable mining method. However, after water injection fracturing, a large amount of coal, water, and gas will be gushed out through the borehole for subsequent coal, water, and gas separation and induction. Transportation and safety guarantees have become urgent issues. At present, there is no relevant targeted device in the country, which makes the hydraulic mining of thin and soft coal seams encounter technical bottlenecks. Contents of the invention [0003] In order to avoid the deficiencies of the prior art, the present invention provides a coal seam drilling coal, gas, and water separation and delivery device, which can not only effective...
