Problems solved by technology

The existing control work for underground coal fires is mainly focused on engineering, and the research work mainly focuses on remote sensing detection and environmental monitoring of fire areas. There is still a lack of special research on the spatial characteristics of underground coal fires for their existence and development. The research on the occurrence and development mechanism of underground coal fires is still very weak, and the lack of basic theoretical research has made it impossible to accurately explain the occurrence and d

Abstract

The invention discloses an underground coal field fire zone typical product dynamic precipitation release simulation experiment system. An underground coal field fire zone product dynamic simulation experiment device is divided into a fissure-containing coal seam geological module, a ventilation module, a fire zone temperature test module and a product detection module according to the experimentprinciple. Each module is arranged in an external protective layer; the ventilation module, by adding an air inlet roadway of a heating belt, inputs hot gas flow and suitable oxygen into the fissure-containing coal seam geological module with air leakage crack design in advance; and the fissure-containing coal seam geological module is connected with the product detection module through an air return way. The simulation experiment system for analyzing the characteristics of the evolutionary products in the coal field fire area is constructed, and the system helps to deepen the understanding ofthe laws of coal fire development, provides theoretical support for the targeted formulation of fire prevention measures, and is of great significance for coal fire control and disaster prevention and control and the like.

Description

technical field [0001] The invention relates to the field of detection of underground coal fire products, in particular to a simulation experiment system for the dynamic precipitation and release of typical products in an underground coal field fire area. Background technique [0002] Underground coal fire is a coal spontaneous combustion phenomenon that occurs on a certain scale due to the combined action of coal and oxygen in the underground broken coal body, which can affect the environment. my country is the country with the most serious coal fire disasters in the world. Coal fires not only burn a large amount of coal resources and affect the development of coal fields, but also produce a large amount of toxic and harmful substances, pollute the environment and destroy ecology. The existing control work for underground coal fires mainly focuses on engineering, and the research work mainly focuses on remote sensing detection and environmental monitoring of fire areas. The...
