Mine underground gas-water slag separation system with dust collecting hood

Abstract

The invention relates to a mine underground gas-water slag separation system with a dust collecting hood. The mine underground gas-water slag separation system with the dust collecting hood comprisesa gas-water slag separation device, a pumping pipeline, a connecting pipeline, a drill pipe, a novel dust collecting hood and a main negative pressure pipeline. The novel dust collecting hood enters the gas-water slag separation device to separate water and slag, and methane gas in coal layers enters the main negative pressure pipeline through the novel dust collecting hood to be pumped away. Themine underground gas-water slag separation system with the dust collecting hood disclosed by the invention is reasonable in structure, ingenious in design, low in cost, light in weight and low in labor intensity for installation, effectively collects and sorts gas-water slag, and is convenient to use, easy to move, and convenient to operate and maintain, and solves the technical problems of greatinconvenience to roadway construction and passing workers caused by cleaning slime slag flowing downwards by punching water and gushing gas in existing coal mine, thereby having very good market prospects and development space for the conventional technology.

Description

technical field [0001] The invention relates to the technical field of mine underground water and slag removal equipment, in particular to a mine underground gas-water slag separation system with a dust collecting hood. Background technique [0002] my country is a country with large coal mine resources. During the process of drilling, mining, screening and transportation, coal mines will inevitably produce a large amount of dust and coal ash, and gas will be released. In the process of mining, high-pressure water is used to make holes in the mining face throughout the process to prevent the problem of mine gas exceeding the limit. However, a large amount of water is used in the process of high-pressure water hole making. Although the dust problem has been solved to a large extent, the problem of coal slime slag cleaning under the punching water flow and gas gushing still exist. [0003] At present, dust hoods are commonly used in mines to collect gas and water slag. Most of...

Problems solved by technology

[0006] In order to solve the problem that existing coal mines generally adopt water conservancy hole-making technology, during the drilling process, high-pressure water is used to make holes on the mining face to prevent the problem of mine gas exceeding the limit

However, a large amount of water will be used in the process of creating holes with high-pressure water. Although the dust problem has been solved to a large extent, the problems of coal slime cleaning under the punching water and gas gushing still exist; Dust collection hoods are used to collect gas and water slag. Most of the existing dust collection hoods are made of iron + copper; the cost is high, the quality is heavy, the labor intensity of the workers is high during installation, and it is very inconvenient to use; generally, water from the mine is used. The slag flows along the roadway to the low-lying collection box. After the water slag is collected, the water seeps out from the gap, and the workers put the remaining coal slag on the belt to transport away; Great inconvenience and other technical problems, the present invention provides an underground gas-water slag separation system with a dust collection cover to achieve reasonable structure, ingenious design, low cost, light weight, low installation labor intensity, and effective collection of gas-water slag And classified processing, easy to use, mobile light purpose
