Stream coupling material is formulated by a certain percentage by paraffin, vaseline, river sand, calcium carbonate and hydraulic oil.
7. a kind of deep fractures Striping noise, filling simulation test method are it is characterised in that comprise the following steps successively：
A lay model-rock stratum, laid after sand, calcium carbonate, gypsum, water are mixed by a certain percentage, rock stratum base plate every
Water layer is laid using solid＆liquid couple material, in process of deployment, places in the same level of rock stratum roof and floor different depth
Some Multifunction Sensors, for monitoring three received strength and the infiltration hydraulic pressure size at roof and floor different depth；Different in base plate
Some baton rounds equipped with calcium oxide particle are placed on the same level of depth；
B then lays model-coal seam above rock stratum, simulates coal seam with the mode of multiple stand under load pneumatophores arrangement, wherein often
Individual stand under load pneumatophore is all connected with filling system；
After the completion of c treats model laying, model is placed in loading case, and displacement constraint is carried out by glass baffle plate, by adding
Loading system applies vertical load and lateral load, and laying rock stratum is carried out with vertical and lateral loading, simulation deep coal rock layer
Stress；
D passes through the stand under load pneumatophore of extraction different interval position, to simulate difference and to adopt wide and stay wide seam mining, and to study not
With adopt stay than seam mining after the stress of roof and floor and change in displacement rule；
E represents seam mining after gas emptying in each stand under load air bag body to be terminated, and is subject to carrier gas using filling system to each
, so that the increase of stand under load pneumatophore volume, bashing, filled system charge is to diverse location for injection filler in utricule
Stand under load pneumatophore after, to study the stress of roof and floor and change in displacement rule after diverse location filling；
F is distributed with several water seepage holes in the bottom loading case, these water seepage holes is connected with water under high pressure osmotic system, artesian water
Through conduit pipe in the flow process of goaf, soak the calcium oxide particle in the baton round being arranged in rock stratum, calcium oxide is sent out
Heat is reacted and discharges in life, now can visit, using infrared detecting set, the position discharging heat, obtains leading of artesian water flowing
Aquaporin path forming process.
