Description
Technical field
This utility model relates to a kind of coal measures pressure-bearing fault activation gushing water similar test technical field, is more particularly to a kind of fluid structurecoupling simulation material for coal measures pressure-bearing fault activation gushing water similar test.
Background technology
Rich coal resources in China, but hosting geological condition is complicated so that and in coal mining, geological disaster happens occasionally.Along with the further increase of coal mining depth and mining rate, stope is day by day serious by the threat of base plate Ordovician karst water, the particularly stope containing fault tectonic, its Water Inrush prediction and to prevent and treat problem the most prominent.
Fault activation gushing water is a kind of important form of mine water inrush, and it has stronger concealment and indefinability, easily causes major disaster, and the safety in production in colliery in serious threat.According to statistics, the mine water inrush accident in the whole nation 80% is caused by fault activation, and the overwhelming majority to be the non-water conductive fault under the conditions of original geology activate under mining influence and the gushing water that induces.The limitation of complexity and research means owing to adopting fault activation mechanism of water inrush, make many mines give over to barrier pillar to prevent from fault activation gushing water from having to abandoning the exploitation of a large amount of coal resources, the most then temporarily cannot exploit because of the threat of Water Inrush.
Similar test is a kind of effective means of research stope fault activation gushing water, its can intuitively during the inverting advance of the face tomography wall-rock crack produce, extend, be formed through the process of water inrush channel, provide certain theoretical foundation and practical advice for prediction and preventing and treating stope fault activation gushing water.
Selecting correct similar materials is the successful precondition and guarantee of similar test, and the R&D institution such as Shandong University, University Of Science and Technology Of Shandong has successively carried out the preparation research of fluid structurecoupling similar materials.Patent (200910017549.0) uses sand and Pulvis Talci as aggregate, paraffin is as cementing agent, it is equipped with appropriate regulator, prepare a kind of analog material for fluid structure interaction mode test, for simulating the rock of different mechanical properties and different permeability, solve tradition analog material water disintegration and a difficult problem for simulation similarity difference；Equally, patent (201310598017.7) also discloses that the adjustable fluid structurecoupling analog material of a kind of model test prepared by normal sand, calcium carbonate, blanc fixe, cement, silicone oil, chlorinated paraffin, water, although the problem that paraffin class analog material solves solid model material water disintegration, but its preparation process is complicated, temperature conditions is required higher, and preparing process is bigger to the performance impact of material, manufacturing cycle is long, is unsuitable for the full-scale model test requirement analog material short cycle and prepares on a large scale and fill.
Further, patent (201110427064.6) utilizes normal sand, blanc fixe, Pulvis Talci, cement, vaseline, silicone oil, appropriate mixing water, prepare a kind of fluid structurecoupling analog material for model test, the cement of this material employing hydraulicity and the vaseline of non-hydrophilic are as cementing agent, solve analog material and meet the problem that water softens disintegrate, the intensity and the elastic modelling quantity that make material can regulate in a big way, meet the needs of fluid structurecoupling similar test simulation material；Equally, patent (201310321229.0) discloses a kind of by sand, cement, Kaolin, vaseline, the analog material tested for middle-size and small-size fluid structure interaction mode of water preparation, and it is applicable to simulate different mechanical properties and the test of infiltrative petrophysical model.
Although the preparation of above-mentioned simulation material considers the Coupling effect of seepage rock deformation of similar test, but often simulation material single only with certain, uniform in similar test, it is difficult to reflection containing face surrounding rock under the conditions of the complex geological structures such as tomography and tomography lithology, permeability, stress and the difference of displacement, the research and development of the complex geological structure similar materials such as shortage tomography.For this, patent (201310104498.1) discloses one by Gypsum Fibrosum as cementing agent, Pulvis Talci, quartz sand, vaseline are as regulator, can be used for simulating the similar materials of tomography fluid structurecoupling characteristic under the conditions of different permeability, it is achieved the real time contrast of same experiment interrupting layer and country rock fluid structurecoupling characteristic.
But the similar materials of above-mentioned preparation cannot be used for coal measures pressure-bearing tomography and adopts the fluid structurecoupling similar test of activation gushing water, trace it to its cause and essentially consist in tomography analog material and water-swellable and permeability need to be occurred under hydraulic action to gradually step up and disintegrate slowly occurs, be difficult to meet the similar of mechanics parameter and water rationality parameter simultaneously.Therefore, the research in past seldom relates to the analog simulation of coal measures pressure-bearing fault activation gushing water, it is impossible to reflection tomography catastrophe evolution under artesian water effect.
For this, patent (201510252670.7) discloses a kind of by Pulvis Talci, sand, Gypsum Fibrosum, bentonite, liquid paraffin, and the similar materials that mixing water forms in right amount, dash forward for simulation tunnel digging process interrupting layer the similar test of mud, solve the problem that analog material occurs slowly to weaken disintegrate under water effect, but its cannot image, intuitively reproduce adopt coal measures pressure-bearing fault crevice produce, extension, through, and finally activation formed conduit pipe dynamic process.
Further, patent (201510432280.8) discloses a kind of analog material for simulating coal mining structure gushing water and preparation using method thereof, this analog material is with Semen Glycines, river sand, calcium carbonate, Gypsum Fibrosum is raw material, can indirectly realize the hydraulic pressure influence to country rock, the initiative of tectonic activization can be simulated, and then simulation structure destruction under coupling activates and shows formation and the evolution of water flowing passage, but cannot analog material be permeated inverting artesian water, wash away the effect producing crack and the process forming water inrush channel thereof, more cannot reflect structure analog material occur under water effect slowly weaken disintegrate.
As can be seen here, existing tomography similar materials await further improving, perfect, to be preferably applied on artesian water adopt the visualization analog simulation research of fault activation and water inrush channel forming process.
Therefore, for liberating substantial amounts of coal resources, ensure the safe mining under safe waterpressure of aquifer containing tomography coal seam on artesian water, simultaneously in view of advantages such as similar test intuitive are strong, motility is good, efficiency is high, reproducible, it is necessary to research and develop the fluid structurecoupling simulation material for coal measures pressure-bearing fault activation gushing water similar test, carry out the similar test research of stope fault activation gushing water Evolution, it is achieved on artesian water, contain the safety and high efficiency in tomography coal seam.
