Description
Technical field
The invention belongs to colliery ground temperature parameter testing field, be related to a kind of device tested for colliery Virgin rock temperature and its
Application method.
Background technology
With the development and the increasingly increase of mineral resources demand of society, and superficial part mineral resources are fewer and fewer, and the world is each
Main mining country subsequently enters deep mining.With the increase of mining depth, ground temperature is also increased.Underground thermal pollution problem is got over
Come more serious, it has also become one of six big disasters arranged side by side with mine gas, fire, dust, top plate, water.So to building mine well
Lower thermal environment situation, profiling temperatures carry out investigation and research, and the region of heat evil may be occurred by primarily determining that, and to this region
Thermal source analyzed and studied, then take effective measures progress improvement ever more important.
The measure of country rock original temperature (i.e. protolith ground temperature) is that underground thermal pollution prevents and treats most important element task, acquired ginseng
Number is to carry out the fundamental parameter that heat source of underground mine analysis and the prediction of underground airflow temperature are calculated, and is also to divide underground thermal pollution grade
Basic foundation.The measure of Virgin rock temperature is generally divided into deep hole thermometry and shallow bore hole quick temperature measurement method.Both approaches are required for
Temperature probe is attached to bottom hole country rock, so all extremely important to techniques such as the protection of thermocouple, feeding and sealing of holes.
Before current protolith shallow well thermometry method is thermometric, temperature probe fixing pipe front cutting is processed, yellow mud is utilized
Fixed temperature probe, during thermometric, first sets an obstacle at temperature probe fixing pipe cut edge and follows ring to wrap up in one section of yellow mud,
Temperature probe fixing pipe is put to bottom hole, yellow mud is hit with push-in extruded tube, is allowed to extend, completion initial envelope closely sealed with hole wall
Hole, is then repeatedly pushed into push-in extruded tube and hits some sections of spaced apart cottons and yellow mud plug, completes final envelope
Hole, finally, connects thermometer measurement rock temperature, until temperature value extracts temperature probe fixing pipe after tending towards stability, completes temperature measurer
Make.The problems such as invention solves conventional shallow well thermometry method temperature probe feeding, extraction and difficult sealing of hole, but it is cumbersome, it is time-consuming
Arduously, and it is not suitable for deep hole thermometric.
Another method of testing is to stretch out RTD metal probe outside plastic tube, is then entered with wire through plastic tube
Trip temperature is tested, when being tested using this method, and RTD is in vacant state, it is difficult to press close to country rock inwall, and the temperature of measurement is real
It is air themperature in drilling on border, easily causes the deviation of measurement result.
In summary, in the prior art still without the original that a kind of cost is relatively low, easy to operate and test effect is ideal
Rock temperature testing method and test device.
