The inhibition of mild steel corrosion in 3% HCl solution by sulfamethoxazole (SZ) and norfloxacin (NF) were investigated at 25 °C using weight loss measurement. measurements reveal that the efficiency grows with increasing concentrations inhibitors, decreases order NF > SZ. adsorption inhibitor molecule on surface follow Langmuir isotherm. Quantum chemical calculation was performed to correlate electronic structure parameters SZ their performances. molecular dynamics simulations applied...
The Yangquan coalfield is one of the typical highly gassy mining areas in China. However, its coal seams are lower permeability, which not conductive to coalbed methane (CBM) drainage. In this study, based on theory ground movement, we analyzed principle and CBM coextraction coalfield, established technology system was further implemented coalfield. technologies “pressure-relief permeability-increase” effect caused by overburden movement can optimally ensure safe efficient improve gas...
Coal dust is a primary contributor to underground coal-mining disasters and also major factor in adversely affecting the occupational health of mine workers. Pre-wetting coal seam with water injection widely considered as one effective means mitigating generation during mining. Injecting through inseam long boreholes parallel working face commonly used technique. However, for most fully-mechanised top-coal caving faces, gas drainage are drilled extract from gassy prior Therefore, there...
As the low permeability of shale gas reservoirs limit its large-scale commercial development, microwave irradiation stimulation is proposed as a new approach to increase reservoir's production. In this study, in order investigate microwave's effect on pore structure, experiments were performed using nuclear magnetic resonance compare size distribution samples before and after treatment. The results showed that numbers well sizes mesopores macropores increased, while number micropores...
Coal and gas outbursts mostly occur during mining at geostructural belts. Pre-drainage coalbed methane using hydraulic fracturing is one of the methods to prevent outbursts. However, coal in belts be soft crushed with special mechanical properties pore structure. To explore feasibility belts, a field investigation on enhanced vertical well was conducted Yangquan Coalfield, China. This case puts forward method for location selection In addition, triple-control technology fracturing, which...
A measurement study was conducted for the effective drainage radius of borehole along coal seam #9 Kaiyuan Coal Mine using gas pressure method and flow method. The results show that 0.75 m, 27 days after drainage, 1.5 92 drainage. Experimental schemes were designed entire evolution stress in mass around borehole, an experimental on methane seepage conducted. Fitting functions permeability sample its vertical obtained by fitting data. Based stress–permeability functional relationship masses a...
