Description
Technical field
The invention belongs to high-temperature mine filling technique fields, and in particular to a kind of high-temperature mine obturation accumulation of heat heat release experiment
Simulator and method.
Background technology
With superficial part mineral resources gradually decrease and it is exhausted, deep mining becomes inexorable trend, and China faces depth at present
The mine of portion's exploitation accounts for about the 90% of national mine sum.With gradually increasing for mining depth, high-ground stress, height will occur
The problems such as ground temperature cause the increasing of exploitation difficulty, operating environment deterioration, aeration-cooling and production cost to sharply increase, so
When deeps mines are exploited, the heat evil problem that safety problem, High-geotemperature caused by high-ground stress are brought has become restriction deep mine
An important factor for bed is effectively exploited.
Mining with stowing artificial supporting mining codes owned by France.In mineral building or nugget, with the propulsion of stope, to mined out
Area is sent into filler, to carry out underground pressure management, control country rock avalanche and surface movement, and in the obturation of formation or at it
Protection is lower to carry out back production, the effective measures pressed to control when being deep mining.With the emission reduction of exploitation of mineral resources process energy conservation and
Environmental requirement is increasingly strict, is the inexorable trend of the following mining development without useless cleaning mining.The method of mining by the way of filling can be by earth's surface heap
Product waste material is backfilling into underground, to greatly improve stoping operation safe coefficient, improves the deep resource rate of recovery 30%, and solve ground
Table accumulates environmental pollution caused by waste material, realizes lasting exploit.
Using filling method carry out deep mining while, if filler using heat accumulation function material, can
To absorb surrounding country rock and the distinguished and admirable heat progress accumulation of heat of stope using its heat storage performance, stope drop is realized while absorbing underground heat
Temperature carries out underground heat exploitation using obturation and realizes stope collaboration cooling.Based on this thinking, it is contemplated that opened in deeps mines
It adopts and carries out work place study in complicated geological environment there are larger difficulty, propose that one kind can carry out " obturation phase-transition heat-storage-heat pump
Unit adopts heat-stope collaboration cooling " experimental system of research, for the extraction and application of underground heat in deeps mines recovery process with adopt
Field cooling research provides possibility.
Based on " obturation phase-transition heat-storage-heat pump unit adopts heat-stope collaboration cooling " thought, by filling slurry and sizing
Phase-change material is mixed and made into accumulation of heat filler and is filled.The heat exchanger tube of underground heat mining system is prefabricated in accumulation of heat filler
In, form obturation after solidification, when accumulation of heat, obturation absorbs heat from country rock and stope, and temperature increases, when temperature is increased to phase
When temperature, phase-change material heat absorption is melted, persistently overheating later extremely close to country rock temperature.When heat release, heat exchanger tube inner cold water passes through
Convection current exchanges heat with tube wall, and tube wall is absorbed heat by heat transfer from obturation, and obturation discharges heat, and temperature continuously decreases, phase transformation material
Expect loss of heat solidification, is gradually cooled to the water temperature close in heat exchanger tube later.Water absorbs obturation thermal temperature and gradually rises in heat exchanger tube
Height constantly takes away filling body heat content, until heat release terminates.Repeatedly, obturation absorbs country rock and stope by heat-accumulating process
Distinguished and admirable heat transfers heat to the water in heat exchanger tube by heat release process, after water temperature increases in heat exchanger tube, then by heat pump unit
Extraction and application, extraction and application and the stope of underground heat cooperates with cooling when realizing mine deep exploitation.
In order to study phase-transition heat-storage obturation when mine deep is exploited thermal extraction and stope cooling in application, need
Theoretical research is first carried out, and when carrying out theoretical research, it is also necessary to it is largely tested, these experiments, if being all put into mine
The practical stope in mountain is done, it will a large amount of manpower and materials is expended, therefore, if can have a set of high-temperature mine obturation accumulation of heat heat release
