Technical Field
The invention relates to the technical field of mine cooling, in particular to a solid waste heat insulation device for the outer surface of surrounding rock of a roadway and a construction process thereof.
Background
With the rapid development of economy and society in China, the large-scale total amount of industrial solid wastes (such as alkaline residues and gold tailings) is increased rapidly. Taking the caustic sludge as an example, the caustic sludge is waste residue discharged in the process of preparing alkali by an ammonia-soda process. The ammonia-soda process for preparing alkali in China can reach 421 ten thousand t/year. 0.3t of caustic sludge needs to be discharged outwards when 1t of soda is produced, and the cost for waste residue discharge is about 1000 ten thousand yuan each year in a factory producing 80 ten thousand of soda each year. In general, the caustic sludge is processed by surface accumulation, and a large amount of caustic sludge is deposited to form a 'white sea', which causes pollution to the surrounding environment. The alkaline residue is effectively utilized, and the waste is changed into valuable, so that the method has obvious social benefit and economic benefit.
The method has important significance in organically combining the solid waste of the alkaline residue and the heat insulation of the deep well tunnel. The method can effectively reduce the discharge of solid waste and isolate the rock temperature of the roadway. Therefore, the development of economical, efficient and practical mine heat insulation methods and technologies to ensure the physical and psychological health of heat-harmed mine workers is a necessary premise for realizing the safe development of deep mineral resources.
Along with the continuous increase of the mining depth of the mine, the ground temperature gradually rises, and the temperature of part of mining working faces of the mine exceeds 30 ℃. The heat damage caused by the high temperature environment of the deep well causes the serious deterioration of the mining operation conditions. According to investigation, the heat source of the high-temperature mine mainly comes from the rock temperature of the wall surface of the roadway. Miners working in high-temperature environment for a long time can cause metabolism disorder, reduce working efficiency and even heatstroke, and workers in important working posts can directly cause mine accidents if the workers have heatstroke.
(1) The traditional mine cooling usually adopts a ventilation mode, but the temperature of a mine roadway is difficult to effectively solve, when the air quantity is large, the cost is not economically saved, and the air flow easily brings dust and flies, so that the environment is polluted.
(2) When the refrigeration method is adopted for cooling, because the temperature of the rock is high, the heat exchange quantity with the roadway is large, a large amount of energy is wasted, and the cooling effect is not good due to a large amount of heat loss.
(3) In the aspect of mine cooling improvement, the heat insulation mode adopted at present is to directly mix part of heat insulation materials into concrete and spray the heat insulation materials on surrounding rocks of a roadway, but the heat insulation effect is greatly reduced and the effect is general.
(4) At present, industrial solid waste of alkaline residues is mainly treated in a surface accumulation mode, and a large amount of alkaline residues can form a 'white sea' after being deposited and cause pollution to the surrounding environment.
The invention aims to provide a method for preparing a heat insulation template on the outer surface of surrounding rock of a roadway by utilizing solid wastes and a construction process thereof, mainly aiming at a high-temperature roadway mainly based on rock temperature.
