Problems solved by technology

However, the water mist or suspended rock powder formed by traditional explosion-proof sheds settles and dissipates quickly, and there is often a mismatch between its duration and the arrival time of subsequent flames, and the explosion-proof effect is poor; and the traditional explosion-proof measures are passively triggered, and the explosion occurs After reaching a certain intensity, it can be activated, which cannot guarantee the effective prevention and elimination of disasters.

Abstract

The invention provides an explosion-proof device and method, and relates to the technical field of coal mine security. The explosion-proof device comprises a detection device which is used for detecting data for explosion judgement, a control device which is connected with the detection device and is used for obtaining the data and analyzing and judging whether explosion occur or not based on thedata, an explosion-proof water shed which is arranged at an explosion spreading path and comprises a water spraying machine and a switch, wherein the switch is used for controlling starting and stopping of the water spraying machine, the switch is connected with the control device, the control device is further used for controlling switching on and off of the switch based on judgement results, andfurther starting and stopping of the water spraying machine are controlled. According to the explosion-proof device, the explosion effect can be improved, and damage of explosion can be effectively prevented and eliminated.

Description

technical field [0001] The invention relates to the technical field of coal mine safety, in particular to an explosion-proof device and method. Background technique [0002] Among the serious accidents in coal mines, gas and coal dust explosions account for a large proportion, often causing serious casualties and property losses. In the prevention and control of underground explosion disaster accidents, in addition to adopting measures to prevent explosions such as strengthening gas drainage and mine ventilation to prevent gas accumulation and preventing underground fire sources, it is also possible to prevent the explosion shock wave from spreading in the early stage of the explosion and eliminate the isolation of the explosion flame. Explosive measures. [0003] The traditional explosion-proof measures are to set up explosion-proof booths in areas where explosions may occur, and hang water bags or rock powder bags. When the explosion shock wave arrives, it will overturn ...
