The invention provides a negative-angle deep-hole intelligent gas extraction and drainage device for a coal mine, and relates to coal mine drainage and gas extraction equipment. The tail end of a main pipe is communicated with a gas drainage pipe, wherein a main pipe valve is arranged on the main pipe, a bypass pipe is arranged at the main pipe valve, the front end and the rear end of the bypass pipe are arranged in the main pipe, the front end of the bypass pipe is connected to the rear end of a water pumping pipe, and the rear portion of the water pumping pipe is arranged in the main pipe and extends forwards from the main pipe to be arranged in water in a drill hole; a sealing ring is arranged between the opening portion of the main pipe and the drill hole; the rear portion of the main pipe is communicated with a water drainage device; the portion, in front of the main pipe valve, of the main pipe is communicated with an air inlet pipe, and an air inlet pipe valve is arranged on the air inlet pipe; the main pipe valve and the air inlet pipe valve are controlled by a timing change-over switch in a control box to be opened and closed; and the main pipe valve is synchronously closed / opened and the air inlet pipe valve is synchronously opened / closed. The negative-angle deep-hole intelligent gas extraction and drainage device has the advantages that the casing pipe technology is adopted, positive-pressure water pumping and drainage and negative-pressure gas pumping are combined into a whole, and therefore gas extraction and drainage work of the drill hole can be automatically and efficiently carried out, and the working efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of coal mine machinery, and further relates to a coal mine water pumping and gas pumping device, in particular to a negative angle deep hole intelligent gas pumping and drainage device for coal mines. Background technique [0002] Coal mining must ensure the safety and efficiency of the mine. In the process of coal mining, in order to reduce the gas content during coal seam mining, advanced coal seam gas discharge has been widely used. The method used is to drill gas drainage holes on the coal wall, where there will be problems with gas and water; Carry out gas extraction and drainage. [0003] The technology of drilling gas drainage and drainage in the prior art is still immature, and many equipments, gas drainage and drainage are separated, and its efficiency is not high, which affects the operation progress and further affects the economic income of the coal mine. Contents of the invention [0004] Th...
