Embodiment Construction
[0007] Between the underground coal mining face 1 and the ground 2, there are several exhaust pipes 3, and a cylinder cover 4 is installed on the exhaust pipes 3. When working, open the cylinder cover 4 above the ground 2 exhaust cylinder 3 to eliminate the gas accumulation on the coal mining face 1, so as to achieve the purpose of eliminating the gas explosion of the coal mining face 1. The number of exhaust cylinders 3 is determined according to the gas concentration and the size of the coal mining face 1 .

The invention discloses method of eliminate gas explosion of coal face, relating to processing technic of coal mine gas. It is equipped with several exhaust pipes between underground coal face and the earth surface, and covers are installed on the pipe. The invention discharge the gas of coal face rapidly preventing the explosion by air convection principles, although this method is not complete scientific, but accords with the small current invest funds purpose. It is concealed when out of work, prevent air pollution, and ensure personal safety. In addition the method can provides water, electricity, food, oxygen, ventilation, call telephony, etc. through exhaust pipes when other underground accident occurred, greatly facilitates to find out the casualties and make personnel and ideological work to provide timely rescue. This method is also applicable to rescue works in other various mining accidents, and solve the too cumbersome and complex problems of the existing devices and methods preventing coal mine gas explosion.
Description
technical field [0001] The invention relates to a coal mine gas treatment technology, specifically a method for eliminating gas explosions in coal mining face. Background technique [0002] At present, in coal mining operations, gas explosions in coal mining face are the most serious disasters in coal mines, which bring irreparable losses to people's lives, property and national economy. However, some existing devices and methods for preventing gas explosions in coal mines are too cumbersome and complicated, and there is no relatively easy method for preventing gas explosions in coal mining faces at present. Contents of the invention [0003] What this invention is to solve is that some existing devices and methods for preventing gas explosions in coal mines are too cumbersome and complicated. At present, there is no relatively simple method for preventing gas explosions in coal mining face. Method for gas explosion in coal mining face. [0004] The technical solution ad...
