Abstract

The invention relates to a gas and dust collecting device, comprising hole sealing components, collecting components and base components which are sequentially connected, wherein the hole sealing components and the collecting components are of hollow structures for accommodating drill pipes. The hole sealing components comprise hole sealing barrels, hole sealing capsules, pieces for fixing the inner sides of the capsules, pieces for fixing outer sides of the capsules, hole sealing flange plates, pipelines in the plates, an externally connected pipeline and hole sealing end covers; the collecting components comprise collecting barrels, a dustproof water pipe, an air water slag outlet pipe and a fixed flange; and the base components comprise a base, sealing ring seats, sealing ring end covers, linings and combined sealing rings. The gas and dust collecting device provided by the invention has the beneficial effects that the phenomenon of ultralimit or continuous deterioration of work environment, caused by the condition that gas or boring mud and dust which are ejected from a drill hole enter an underground tunnel, is avoided.

Description

technical field [0001] The invention belongs to the technical field of coal mining, and in particular relates to special equipment for coal mines that effectively collects the gas and compressed air exhaust powder dust sprayed out of the borehole during the drilling construction process, and prevents gas overrun and dust hazards during drilling. . Background technique [0002] Coal mine gas and dust accidents are one of the major underground disasters. If a gas and dust accident occurs, it will not only seriously damage the production environment, but also cause casualties, causing huge losses to the people, enterprises, and the country. Therefore, the elimination of gas overrun Gas and dust are the preconditions for preventing gas and dust accidents, and are also one of the important guarantees for safe production in mines. [0003] Due to geological deposition, a large amount of gas and other toxic and harmful gases have accumulated in the coal seam. In order to realize s...
