Abstract

The invention discloses a digital coal dust flame length measuring system during instantaneous explosion comprising a high temperature heating ignition sub system for igniting the cost dust, a dust sending sub system for sending coal dust to the high temperature heating ignition sub system, a sub system for photographing flame image during instantaneous explosion and collecting data and a main control unit; the dust sending sub system and the high temperature heating ignition sub system are connected electrically with the main control unit and controlled by the same. The sub system for photographing flame image during instantaneous explosion and collecting data is connected electrically with the main control unit and outputs collected image data to the main control unit to be processed. Furthermore, the invention discloses a digital coal dust flame length measuring method that uses computer image processing analysis technique to analyze flame generated by explosion. Compared with prior judging technique, accuracy and scientificity are improved greatly and judging result is object and fair.

Description

Technical field

[0001] The invention relates to the field of mining coal sample detection equipment and methods, in particular to a digital coal dust explosion instant flame length measurement system and explosive measurement method. Background technique

[0002] my country is a large coal-producing country. At present, it has been found that the coal-bearing area is about 55,000 square kilometers. The coal content accounts for about 11.1% of the world's coal resources, ranking third in the world. However, since most of the coal mines in our country are deep-well coal mines, there are many problems while producing high output. Among them, the problem of coal dust is one of the disasters that have plagued the coal system for a long time. The generation of coal dust exists in all aspects of coal production and transportation.

[0003] Excessive coal dust concentration may cause explosion. Although it is not common for coal dust concentration to reach the lower limit of explosion, it...
