| titleOfInvention | The crack evolution test method of floor strata solid＆liquid couple material |
| abstract | The invention provides the crack evolution test method of floor strata solid＆liquid couple material.It solves the problem of can not really realizing solid＆liquid couple analog simulation.The present invention comprises the following steps：1 weighs sand, paraffin, hydraulic oil, pitch, calcium carbonate and vaseline in proportion；2 by paraffin, hydraulic oil, pitch and vaseline heating and melting and stir；3 stir sand and calcium carbonate addition together；Material is tamped shaping and is stripped standing by 4；5 progress mechanical property tests simultaneously record nature and characteristic；6 choose the approximate ratio of suitable material；7 repeat 1 to 3, complete simulation bottom plate；8 are placed in simulation bottom plate in bottom plate rupture simulation test device；9 apply hydraulic pressure, observe and record simulation coal seam floor failure rule and crack evolution Feature.The material that the present invention is developed can preferably keep the physical and mechanical properties of model test analog material, while meeting solid deformation two conditions similar with permeability, good result is obtained in experiment of developing in crack. |
