A mobile excavation roadway cooling equipment

Abstract

The invention discloses a mobile excavation roadway cooling device, which includes an air supply roadway and a mobile platform, the mobile platform is movably arranged in the air supply roadway, and a heat insulation board is arranged on the mobile platform, and the inner side of the heat insulation board is arranged There are cold radiant aluminum plates with copper tubes, and the cold radiant aluminum plates with copper tubes include radiant aluminum plates and cold water copper tubes, and several cold water copper tubes are equidistantly arranged on the radiant aluminum plates; both the mobile platform and the mobile cold source of the present invention are movable It can move forward according to the advancement of the excavation face. The invention reduces the heat transfer from the peripheral rock of the air supply roadway to the main roadway by adding a heat insulation board outside the radiant aluminum plate, and isolates the heat transfer from the surrounding rock to the main roadway. Humidity transmission, and a cold water copper pipe is integrally formed on the radiant aluminum plate. The cold water supply pipe and the cold water return pipe are connected to the mobile cold source. A temperature sensor is installed on the cold water supply pipe to control the water supply temperature at 15°C, which can effectively reduce the air flow temperature. and humidity, which can improve human thermal comfort.

Description

technical field [0001] The invention relates to the technical field of mine cooling, in particular to a mobile tunnel cooling equipment. Background technique [0002] With the increase of mine mining depth and the continuous improvement of mechanization, mine heat damage has become increasingly prominent, which has become one of the major issues restricting mine safety mining. By 2010, 35% of coal mines in China will have air flow temperatures exceeding 30°C at the mining face. According to the current situation of resource exploitation, the mining depth of China's coal mines is increasing at a rate of 8-12m per year, especially the mines in eastern China are developing at a rate of 100-250m per 10 years. In recent years, a number of mines have mining depths exceeding 1000m. It shows that in the main coal distribution areas in China, the temperature of the rock strata below 1000m reaches 35-45°C, and the temperature of the rock strata below 1500m exceeds 45°C. "Several Regul...

Problems solved by technology

[0005] Throughout the domestic and foreign methods of controlling mine heat damage, they can be generally divided into non-artificial cooling methods and artificial cooling methods. The former mainly increases the air volume, changes the ventilation mode, avoids local heat sources, pre-cools the air flow, and isolates high temperature. Surrounding rock and hot water prevention and control have successfully achieved non-artificial cooling, but improving ventilation methods and increasing air volume are affected by the temperature of the inlet air and surrounding rock, and the cooling range is very limited. The latter mainly uses mine air conditioners for cooling and cooling. : local air conditioner, underground water source heat pump air conditioner, mine air refrigerator, ground centralized type, underground centralized type, ice-cooling cooling system, etc., ground centralized type, underground centralized type, ice-cooling cooling system, etc. The system is more complicated and the initial investment is large , high operating cost, large amount of installation and maintenance engineering, mainly used for cooling large mines with a cooling capacity of more than 5000k W, while other mine artificial cooling cooling methods are suitable for some small production mines with a cooling capacity of 3000k W, centralized refrigeration Another significant defect of the main mine cooling method is that the long-distance transportation has a large amount of cold loss. According to the conditions of Suncun, Pingba Mine and foreign countries, the system cold loss can reach 20%. Therefore, the present invention proposes a mobile Type tunneling roadway cooling equipment to solve the problems existing in the prior art
