It is essential to evaluate the blasting-enhanced permeability (BEP) feasibility of a low-permeability sandstone-type uranium deposit. In this work, mineral composition, reservoir physical properties and rock mechanical samples from deposits were first measured. Then, reformability evaluation method was established by analytic hierarchy process-entropy weight (AHP-EWM) fuzzy mathematics method. Finally, results verified split Hopkinson Pressure Bar (SHPB) experiment test. Results show that...
CO2 injection to enhance coalbed methane (CO2-ECBM) production is a promising technology for realizing the efficient exploitation of new energy resource, but its effect cooperatively affected by miscellaneous influencing factors. To elucidate mechanism and increase efficiency displacement CH4 CO2, flooding experiments under influence pressure, confining temperature were conducted. The results show that an in pressure enlarges pore-fracture network coal matrix promotes gas adsorption ability...
CO 2 + O in situ leaching has been extensively applied uranium recovery sandstone-type deposits of China. The geochemical processes impact and constrain the reaction solution migration; thus, it is necessary to study –water–rock process its influence on physical properties uranium-bearing reservoirs. In this work, a simulation experiment was carried out, mineralogical multiscale pore characteristics typical samples before after were compared by X-ray diffraction high-pressure mercury...
Guaranteeing CO 2 injectivity has been the precondition for implementing -enhanced coalbed methane recovery (CO -ECBM), however, it dramatically decreases during injection process because is influenced by dynamic change of anisotropic permeability coal. To reveal and evaluate coal, test simulation were first conducted, then corresponding numerical models established verified experimental data. The results show that coal in parallel face cleat direction largest, followed butt vertical bedding...
In situ leaching (ISL) is becoming the main mining practice for sandstone-type uranium deposits in China. The key to ISL technology aid solution contacting ore bed over a large range, which will induce series of chemical reactions extract uranium; thus, it essential thoroughly understand reservoir physical properties deposits. Taking Qianjiadian (southern Songliao Basin, China) as an example, mineral composition and pore structure samples different layers were measured using X-ray...
Backfill mining is an effective way to solve environment pollute, surface subsidence, and groundwater system damage which caused by coal mining. However, the complex underground may change physical mechanical properties of backfill body, poses a risk strength failure. This paper analyzed failure gangue-based cemented body made up gangue fly ash. The results show that physicochemical reactions will generate quartz, kaolinite, other high-strength substances; hydration reaction between fine...
When rockfall occurs along dense rock slopes, the rotation direction of is not always downhill. Specifically, may obtain a reverse speed (RRS) after impact under certain conditions, effect which on restitution coefficient ( RC ) cannot be ignored. According to statistical results (RR) phenomena blocks obtained from previous experiments, occurrence RR correlated block shape, incident angle, and contact attitude. In this study, considering typically shaped cubic block, critical condition for...
