Description
Technical field
The utility model relates to the down-hole paste body filling simulation system of using in the test room.
Background technology
Mineral resources are non-renewable wealth, are the important substance bases of national economy and social development, and current mankind has caused serious mining damage and environmental destruction to the great demand and the large-scale exploitation of mineral resources.Clearly proposition of Sixteenth CPC National Congress report " ... walk out a new industrialization way high in technological content, good in economic efficiency, low in resources consumption, low in the pollution of the environment, that advantage of human resources is not fully exerted.”。Therefore, at the china natural resources relative shortage, the basic characteristics that environment is relatively more fragile, it is imperative to set up the resources conservation, the eco-friendly industrialization road that are fit to China's national situation.And world leaders, environmentalist and mining expert wish that also mining industry realizes zero-emission and do not destroy ground surface environment.Therefore alleviating the destruction of mining industry to natural environment, fully recycle Limited resources, is to need a great environmental protection task in a planned way finishing in China and even the world wide.On this basis, the Qian Minggao academician of China Mining University has proposed the technical system of " green exploitation ", is exactly from the angle understanding of broad sense resource on its basic conception and treats all utilizable resources such as coal, gas, water, soil; Basic point of departure is to prevent to alleviate as far as possible the harmful effect that cuts coal to environment and other resources from the angle of mining.
Be pressed with a large amount of coal resources under the ground building of China's One's name is legion, railway, the water body, according to the incomplete statistics to national emphasis colliery, China's " three times " at present presses coal 137.64 hundred million t, and building presses down coal 94.68 hundred million t, 23.91 hundred million t under the railway, water body press down coal 19.05 hundred million t.According to the statistics of Shandong Province, buildings such as Shandong province village press down coal and reach 4,400,000,000 t, account for 53% of recoverable reserves.Only Jining City's high seam presses the coal village just to have 3600, and what needed before 2012 to move just reaches 564.Dragon is solid, disposable 12 and 11 villages of resettlement that just need of Zhao building mine first exploiting field exploitation.For a long time, China " builds down " and presses coal mining mainly to adopt village resettlement, band exploitation and this several method of overlying strata separation layer grouting, and, wherein 75% finish by village resettlement.But the method for village resettlement at present more and more difficulty is carried out, the one, and land acquisition expense in recent years is high, and the removal charge rising all the way has brought heavy financial burden for colliery enterprise; The 2nd, because the distance of village resettlement is excessive, brought many productions and inconvenience in life to the peasant, the peasant is unwilling to move.Strip coating method and overlying strata separation layer grouting method can play the certain minimizing subsidence and the effect of mining damage really, but the recovery ratio of strip coating method only is 40～60%, serious waste of resources, the subsidence deflection that the overlying strata separation layer grouting method can reduce is no more than 40%, can not reach substantially that surface deformable is little, the non-destructive purpose of building.Above-mentioned condition has also caused very adverse influence for the exploitation of coal resources in China, so press for a kind of coal-mining method new, that can realize high-yield and high-efficiency, Environmental Safety, the above problem of processing of development.
Adopt solid waste such as gangue, flyash, slag, be aided with cementitious materials manufacture on ground no critical flow velocity, not bleeding, do not precipitate, have paste slurry good pump-conveying property, can the low speed line transportation.The characteristics of this lotion are that cost is low, initial stage can reach uprightly, and the middle and later periods can support overlying rock fully, utilize the filling pump by line transportation to the down-hole, bashing forms the modern mining method and the technology of propping up the control system based on the overlying strata of paste body filling in good time.Gangue paste consolidated fill technology has well solved pollution and stacking problem, the mining damage problem in colliery, " three times " of gangue and has pressed the coal problem; be not damaged at the protection groundwater resources simultaneously; improve coal recovery rate, improve aspect performance significant role such as Mine Safety in Production condition.Therefore, produced on-site is actual will to have crucial economy, society and environment protection significance to instructing in the on-the-spot paste body filling of development laboratory simulation system.
