Method for controlling high temperature stope face operating region environment temperature by means of cold wind separation curtain

Abstract

The invention belongs to the field of air conditioning engineering, and relates to a method for controlling high temperature stope face operating region heat damage by means of air distribution. A cold wind separation curtain device system and a wind temperature and wind pressure monitoring control system are employed. The cold wind separation curtain device system is employed to carry out barrier-free separation on the exploitation region and the operating region of the stope face in order to control stope face operating region heat damage. The method for controlling high temperature stope face operating region heat damage by means of air distribution is characterized in that by continuously arranging air distributors on the top specific positions of the air intake tunnel and the stope face to feed cold wind downwards, a cold wind curtain is formed between the exploitation region and the operating region of the stope face, the tunnel wind current is cut along the axis vertical face, influence of a high temperature heat source in the exploitation region on the operating region is prevented, and at the same time, a stope face operating region temperature and cold wind port static pressure monitoring system is laid to examine the cutting, heat-insulation and cooling effect of the cold wind curtain. According to the invention, the problem that the environment temperature of the stope face operating region affected by the high temperature heat source is hard to control can be effectively solved, and the fact that the stope face normally operates is guaranteed.

Description

technical field [0001] The invention belongs to a method for controlling heat damage in the working area of ​​a mining face affected by a high-temperature heat source, and is suitable for a mining face whose working environment temperature exceeds the standard due to the influence of a high-temperature heat source. Background technique [0002] With the increase of mine mining depth and the improvement of mining mechanization, more and more mines in my country have experienced high temperature heat damage. The problem of high temperature heat damage has become one of the natural disasters commonly faced by deep mine mining. According to relevant statistics, there are currently more than 30 pairs of mine mining face air flow temperatures above 30°C in China, and some even as high as 37°C. Safe and efficient mining of coal mines. [0003] In order to solve the problem of mine heat damage, at present, many mines with high temperature heat damage have adopted mine cooling syste...

Problems solved by technology

In this way, although the cooling process is relatively simple, it often results in a large temperature difference between the air entering and returning to the working face, high installed cooling load of the cooling system, high energy consumption, and poor cooling effect, which cannot fundamentally eliminate the heat damage of the working face to the operators. serious threat to the physical, mental and physical health and safety of
