Description
Technical field
The invention belongs to high temperature deep well goaf filling technical field, and in particular to a kind of high temperature depth with cooling function
Well goaf filling slurry pipeline transport system and method.
Background technology
As superficial part resource is gradually decreased and exhausted, mining depth is increasing, and current China faces the ore deposit of deep mining
Mountain accounts for the 90% of national mine sum；Deep mining faces the problems such as high-ground stress, High-geotemperature, hyperosmosis, causes out
Adopt that difficulty is increased, operating environment deteriorates, aeration-cooling and production cost is sharply increased, be that deep resource exploitation proposes sternness and chooses
War；To realize keeping the safety in production, applying for filling technique is essential in deep resource exploitation, and the method for mining by the way of filling can be by earth's surface
Pile up waste material and be backfilling into underground, process dead zone, so as to greatly improve stoping operation safe coefficient, improve the deep resource rate of recovery
30%, and the environmental pollution that accumulation on ground surface waste material is caused is solved, realize lasting exploit；And solve the problems, such as mine high-temperature also oneself compel
The eyebrows and eyelashes, filling has certain help to exploiting field cooling aspect, and filling can greatly reduce stope protolith exposed area, so as to reduce
The area of dissipation of protolith, therefore can reduce the heat of protolith and distribute；Physical efficiency is filled simultaneously effectively prevents distinguished and admirable seepage,
Avoid useless wind to connect to a certain extent, so as to improve distinguished and admirable utilization rate, effectively reduce temperature in hole；Deep-well filling technique face
Face many problems, paste body filling is a following big Main way, and traditional slush technique, pulp density is difficult to bring up to
More than 70%, and generally need to carry out graded desliming to tailings, the result is that the utilization rate of tailings is low, after being filled with stope
