“…Response surface methodology (RSM), which is a combination of mathematical and statistical techniques, is widely applied for analyzing the influence of various factors on one system (Liu et al, 2015a;Sodeifian et al, 2014;Kirmizakis et al, 2014). To explore the relationship between the borehole radius (X 1 ), the initial pressure (X 2 ), the original permeability (X 3 ) and gas drainage effects, a mathematical model was designed using Design Expert 8.0.5b software.…”

“…There was only a 0.01% chance that a large "Model F value" could occur due to noise. Values of "Prob > F" less than 0.0500 indicate that the model terms are significant (Sodeifian et al, 2014). In this case A, B, C, B 2 are significant model terms.…”

“…Response surface methodology (RSM), a collection of mathematical and statistical techniques, has been found to be a functional aid in exploring the interactions of multiple factors on the response of a system (Kirmizakis et al, 2014;Sodeifian et al, 2014;Yuan et al, 2015). During an analysis, it is very important to select an appropriate method that can evaluate the influence of independent variables and their coupled effects on the dependent variable with fewer experiments.…”

“…During an analysis, it is very important to select an appropriate method that can evaluate the influence of independent variables and their coupled effects on the dependent variable with fewer experiments. RSM provides a great deal of information with only a small number of tests to monitor the interactions among variables on the response (Sodeifian et al, 2014;Kirmizakis et al, 2014).…”

a b s t r a c tHydraulic slotting is an effective method for enhanced coalbed methane (ECBM) recovery, and it has been widely employed in China. Although there have been many studies of this technique, the influence of slot parameters on the strength characteristic of the coal, which is an important factor that affects the permeability enhancement effect, has rarely been studied. Thus, only limited information is available regarding the pressure relief and permeability enhancement mechanisms of this technique. In the current study, the influence of flaw parameters on the compressive strength of a precracked sample under biaxial compression is discussed. The results indicate that an increase in the flaw length and width has a negative effect on the compressive strength, whereas an increase in the flaw inclination angle has a positive effect on the compressive strength. The results of the response surface methodology (RSM) indicate that the interactions among the flaw parameters have a significant influence on the compressive strength. The propagation patterns of cracks are quantified by the fractal dimension, which is used to explore the mechanism of compressive strength variation with changes in the flaw parameters. The study results indicate that the variation in the flaw parameters changes the propagation pattern of cracks, resulting in different compressive strengths. In addition, an opposite variation trend of the compressive strength and fractal dimension with flaw parameters is also observed. The research results are expected to guide the field application of hydraulic slotting.

Chemists and industrialists are continuously attempting to develop greener and more environmentally benign chemical processes to extract essential oils and bioactive metabolites of high purity, finding various applications in cosmetics, detergents, nutraceuticals and pharmaceuticals. An increase preferenced for natural products over synthetic ones has made supercritical fluid technology a primary alternative for the generation of high‐value bioactive ingredients. This effective technique requires only moderate temperatures, eliminates clean‐up steps and avoids the use of harmful organic solvents. In this context, our study was focused on the chemical analysis of Calamintha nepeta subsp. nepeta aromatic extracts obtained with supercritical carbon dioxide. The effect of different operating conditions on the capacity of the lipophilic solvent to extract the targeted volatile components was also studied. The process was carried out at a fairly low constant temperature of 40°C, and with varying the pressure from 90 to 300 bar. The chemical composition of the extracts was analyzed by gas chromatography–mass spectroscopy. The results showed that the composition pattern, the concentrations of individual components and the quality of the extractable analytes were affected by pressure increase. The extraction yields varied from 0.73 to 1.21 wt% at 90 and 300 bar, respectively.
