Description
Technical field
The present invention relates to a kind of heat sink, be specifically related to a kind of colliery high temperature digging laneway segmentation heat sink and coolingMethod.
Background technology
In recent years, along with the pit mining degree of depth continues to increase, ventilation distance constantly extends, ventilation section is little etc. many because ofElement, can not meet the requirement of down-hole required airflow, causes down-hole temperature to raise, and produces high warm evil, to a great extentThe contradiction that is unfavorable for safety in production with mining sequence, work situation etc. is particularly outstanding. In hot environment, people's central nervous systemSystem is imbalance easily, thus feel absent-minded, tired, all over the body unable, have dizzy spells, etc. This state of mind becomes brings outThe reason of accident. In the time that the air themperature of operating location in ore deposit reaches 30 DEG C, start to occur heatstroke death by accident. At high-temperature mineIn, general productivity ratio is all lower, and its relative efficiency of some mines is only 30 one 40%. " safety regulations in coal mine " regulation: " rawThe air themperature of producing coal mine excavation working face must not exceed 26 DEG C " " air themperature of getting working face exceedes 30 DEG C and must takeCooling measure. " for the problem of the high warm evil of down-hole, successively taked optimization ventilating system, strengthen face air volume, changedAscensional ventilation is the measures such as descentional ventilation, coal-bed flooding precooling coal body, ice cube dissolving cooling, but effect is all not too remarkable.
By field investigation and reading relative literature, draw following existing mine cooling measure:
1. pair existing ventilating system is adjusted. The problem existing: in the time that air quantity is increased to a certain degree, the cooling of increasing windEffect will weaken. Increase the restriction that wind cooling is also subject to the many factors such as mine section and ventilation blower ability, range of application simultaneouslyReduce. Certain ore deposit downhole temperature exceedes 28 degrees Celsius of " safety regulations in coal mine " defined, and aeration-coolingly can not solve essenceProblem.
2. take provision for thermal insulation. The problem existing: expense is higher, and timeliness is poor, As time goes on, spraying heat insulationThe heat-blocking action of layer can reduce greatly. Also can produce the unsafe factors such as fire, toxic gas release simultaneously.
3. pair air intake is lowered the temperature in advance. The problem existing: can increase the humidity of air intake, can cause moist operating environment.Summer, ambient temperature was higher, was difficult to reach the required refrigerating capacity of mine, so cooling-down effect is not obvious.
4. descentional ventilation. The problem existing: descentional ventilation mode is unfavorable for gas management and the fire period in working faceCatastrophe processing; In addition, transport electromechanical equipment is all in return, has brought unsafe factor to production. Therefore, adoptWhile using descentional ventilation, must adopt corresponding safety measure, have certain limitation.
5. individual protection. The problem existing: workman job site disperses relatively, and conventional cold accumulation cooling-down takes workman is enteredRow protection, cold accumulation cooling-down takes due to needs agent for storage of coldness and freezing, and heat exchange is very fast, and the seeervice cycle is shorter. There is the cycle in agent for storage of coldness, manyAfter inferior use, will lose efficacy. Being difficult to meet high-frequency uses.
Find by analysis, above existing mine cooling measure, can not effectively lower the temperature to down-hole. CauseThis, the method and apparatus that is necessary to invent a kind of effective down-hole cooling is realized mine cooling, especially to workspaceBetween cooling.
Summary of the invention
For problems of the prior art, the invention provides a kind of colliery high temperature digging laneway segmentation heat sink andCool-down method, utilizes compressed air to realize down-hole working face cooling, and mode by intelligent control module control is to manyDuan Jiangwen unit lowers the temperature, thereby realizes personnel's operation interval cooling in the high temperature digging laneway of whole colliery, can allow down-holeStaff is in the air ambient of relative low temperature.
