Description
Affiliated technical field
The utility model relates to mine laneway country rock heat transfer analogue experiment installation, especially is suitable for test deep heat evil mine country rock body or coal body diabatic process and simulation resolution.
Background technology
Coal is the main body energy of China, has important strategic status in socio-economic development, and the reserves of its buried depth below km have 2.95 * 10
5Hundred million tons, account for 53% of coal resources in China total amount.Along with the long-term large-scale development of mineral resources in recent years, bury in the high-grade mineral products resource of superficial part exhausted day by day, large quantities of collieries and non-coal mine carry out the transition to deep mining, cause the mine working environment quite abominable, if can adopt correlative protection and refrigeration cool-down measure, then the deep thermal environment be can obviously improve, thereby health, the sustainable development of coal industry promoted.
The most collieries in China East China and North China enter the deep, and under Mining in Deep-lying Conditions, it is the major reason of underground work worsening condition that the rock mass initial temperature raises, and lasting high temperature will cause great injury to personnel's health and ability to work.Also reduce the serviceability of underground equipment simultaneously, reduce service life of equipment.Chinese coal is built association and has been organized to set up " the heat evil is prevented and treated design specifications under the coal mine " in 2007, and also the maximum temperature of each work place under the coal mine has been made specified in more detail in " safety regulations in coal mine " (2007 revised edition) that State Administration of Quality and Technical Supervision formulates.Therefore, administer the line correlation research of going forward side by side for underground thermal pollution and become inexorable trend.The protolith temperature height of deep mining is and the most tangible difference of superficial part, also is to the most important influence factor of deep heat evil mine thermal environment.For high temperature country rock body inside and country rock and distinguished and admirable between diabatic process study, seek country rock important prerequisite work inner and that administer with the heat evil that distinguished and admirable relevant heat-transfer mechanism is current high-temperature mine.
Summary of the invention
Technical matters: the purpose of this utility model provides a kind of good leak tightness, and compact conformation is reasonable, can realize the mine laneway country rock heat transfer analogue experiment installation of many country rocks temperature boundary and many air intakes parameter.
Technical scheme: mine laneway country rock heat transfer analogue experiment installation of the present utility model, the model main body that comprises the simulation coal mine roadway country rock body that is located on the model support, the outside of model main body is provided with attemperating unit, the middle part is provided with the simulation tunnel of penetration model main body, the model main body is provided with the refrigeration ventilation unit, be furnished with several thermopairs that link to each other with data line in the model main body, the import and export in simulation tunnel all is provided with the temperature sensor and the air velocity transducer of image data, each data line converges through signal line is defeated by data acquisition unit, passes to coupled computing machine through data acquisition unit and handles.
The hot water constant temperature bag that described attemperating unit is covered by model main body outside surface, Temperature controlled heater that links to each other with the hot water constant temperature bag and flow control valve constitute; Described refrigeration ventilation unit is by refrigeration machine, and the air cooler that links to each other with refrigeration machine, the connecting pipe that passes the simulation tunnel that links to each other with air cooler, the air exhauster that is connected the connecting pipe other end constitute.
Beneficial effect: select for use and the similar similar mediums of coal mine roadway country rock body, form the simulation tunnel by digging process, be consistent with colliery scene tunnel forming process. can simulate easily under the different surrounding rock temperature by different parameters distinguished and admirable after, the temperature field of airflow temperature and country rock body distributes. when fixing a kind of country rock body temperature is spent, by changing the air intake parameter, can test surrounding rock body temperature field, tunnel distribution situation and go out distinguished and admirable correlation parameter. when change country rock body temperature is spent, same by changing the air intake parameter, test country rock body temperature field and go out airflow parameter, draw and the corresponding optimum air intake parameter of country rock body temperature degree. its good leak tightness, compact conformation is reasonable, simulate effect is good, has practicality widely in the present technique field.
