Intelligent explosive gas detection system for fully mechanized coal mining face

Abstract

The invention relates to the technical field of underground explosion prevention, and provides an intelligent explosive gas detection system for a fully mechanized coal mining face. The intelligent explosive gas detection system comprises a ground control unit, a gas concentration detection unit and a suction unit, wherein the ground control unit is used for receiving detection data of the gas concentration detection unit and analyzing and judging whether the detection result exceeds a preset value or not; if the preset value is exceeded, a starting signal is sent to the suction unit; the gas concentration detection unit comprises a detection box; and a plurality of gas probes are respectively arranged on two side walls of the detection box. Therefore, the dust concentration is detected in real time through line patrol of the gas concentration detection unit; the ground control unit receives the detection data of the gas concentration detection unit and analyzes and judges whether the detection result exceeds a preset value or not; if the preset value is exceeded, a starting signal is sent to the suction unit; real-time monitoring on the underground gas concentration and accurate air suction are achieved; and the operation cost is effectively reduced while the operation efficiency of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of underground explosion protection, and in particular relates to an intelligent detection system for explosive gas in a fully mechanized mining face. Background technique [0002] In recent years, intelligent mining has gradually become popular in various mining areas. According to the concept of "safety with few people and safety with no one", through equipment upgrades, intelligent mining at the mining face can realize operations with few or no people. Especially in areas with serious rock burst disasters, the implementation of intelligent mining is particularly important. [0003] Taking Shandong as an example, there are 41 rock burst mines, accounting for nearly 30% of the country's total. Among them, there are 20 places with a mining depth of more than 1,000 meters, accounting for 86.9% of the country, and are the provinces with the most serious rock burst disasters in the country. Since 2011, many r...

AI Technical Summary

Problems solved by technology

Since 2011, many rock burst accidents have occurred, causing a large number of casualties, with huge impact and profound lessons

However, there is a high risk of explosion underground. Although the implementation of intelligent mining has effectively reduced the number of underground operators, there are many underground equipment. Once an explosion occurs, the equipment will be damaged, affecting production and causing serious losses.

[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
