Simulated climate chamber of underground coal mine thermal environment and test method

Abstract

The invention provides a simulated climate chamber of an underground coal mine thermal environment and a test method. The simulated climate chamber is provided with a control cabinet, a first computer, a temperature-humidity system, a fresh air system, a simulated air system, a human body micro-climate acquisition system, an alarm system, and a human body physiological index test system. The simulated climate chamber comprises an experiment preparation room, a test room, and an equipment room. The test method of the simulated climate chamber consists of four steps. Through the simulated climate chamber, personal protection cooling suits for mine and protective properties of the cooling suits can be subjectively and objectively evaluated. Through the simulated climate chamber, the underground coal mine thermal and humid environment can be relatively really simulated; comparatively accurate data is provided; and environment uncontrollability during a live environment test is avoided. The simulated climate chamber and the test method can meet practical operational needs.

Description

technical field [0001] The invention belongs to the technical field of coal mine safety equipment, and in particular relates to an underground coal mine thermal environment simulation climate chamber and a testing method. technical background [0002] As the mining depth of coal mines gradually increases and the degree of comprehensive mechanization continues to increase, the heat emitted by geothermal heat and underground equipment to the underground air increases significantly, and there are more and more high-temperature mines. High temperature heat damage has become the sixth natural disaster after the five natural disasters of water, fire, gas, coal dust and roof. Miners have been working in the mine for a long time in a heat-damaged environment, and the central nervous system is particularly prone to disorders, resulting in trance, fatigue, weakness, and drowsiness. This not only seriously endangers the health of miners, but also becomes an important cause of accidents...

AI Technical Summary

Problems solved by technology

Therefore, there is no ready-made thermal protective clothing on the market that can be directly applied

2. Because of the particularity of the coal industry, many thermal protective clothing researchers are not familiar with the thermal environment of the coal industry

3. Is the thermal protective clothing developed suitable for this industry? Due to the danger of the coal industry, it cannot be directly taken to the coal mine for trial use, and there is a lack of pilot test links

At present, the coal mine industry mostly adopts centralized refrigeration, cooling, and heat removal layout on the ground, which has problems such as "large investment, long construction period, high loss, low efficiency, high operating cost, and ineffective cooling effect"
