Abstract

The invention relates to the field of explosion prevention and explosion suppression under mines, provides a mine comprehensive intelligent gas detection early warning method and a mine comprehensive intelligent gas detection early warning system and solves the problem of low detection accuracy caused by limit of the current gas detection method. The system comprises a data acquisition module and a controller. The data acquisition module is used for acquiring environment information of a coal mine, and the controller comprises an initialization module, a preliminary judgment module, a comprehensive judgment module and a complementary judgment module. By applying the mine comprehensive intelligent gas detection early warning method and the mine comprehensive intelligent gas detection early warning system, precise detection on hidden danger of gas explosion under the coal mine is realized, and thus gas explosion can be prevented or inhibited by taking pertinent measures on the basis of the detection information.

Description

technical field [0001] The invention relates to the field of explosion prevention and suppression in underground mines, in particular to a comprehensive intelligent gas detection and early warning method and system for mining. Background technique [0002] Existing coal mine detection and early warning technologies are mainly based on independent gas concentration detection or individual special gas detection. The individual gas concentration detection can provide the system with gas concentration information. After exceeding the pre-set early warning value, the subsequent corresponding control measures will be implemented to suppress the gas explosion. [0003] Existing detection techniques have the following defects: [0004] (1) Since the gas explosion limit is not static and is related to data such as temperature, pressure, and coal dust concentration, existing measurements cannot accurately determine whether the measured gas concentration is within the gas explosion co...
