This study is the first to observe long-term (1.5 years) succession of microbial communities in a coal seam in response to biostimulation for biogas production. It was conducted in a gas-free sulfate-rich subbituminous coal seam resulting in confidence that all gas produced resulted from the st...
The expression for the damage variable D(σ,h,t) is obtained by substituting Eq. (12) into Eq. (10). A creep damage model for coal–rock combinations is established from the above, as shown in Fig. 15. Figure 15 Fractional creep damage model. Full size image The following assumptions ...

Under this tri-axial compression, the deviatoric stress Δσ is defined as:(8)Δσ=σ1−σ3 The damage constitutive model of coal considering effects of confining pressure and temperature can be obtained by combining the generalized Hooke's law and Eqs. (1), (2), (6), (8):(9)Δσ...
The Pingshuo mining area has changed significantly from the construction of the mine in 1986 to 2018, and the land use conversion is obtained through ArcGIS software (Table 3). From 1986 to 2018, the arable land in the Pingshuo mining area is converted into 14,085.34 ha, of which 30.4%...
Today and into the foreseeable future, coal is and will be a principal source of energy, which is needed to provide a foundation to sustain the advancement of human civilization. With the development of modern industrial civilization that was derived from the exploitation and application of fossil...
Even though there are several limits for probing the micropores of porous media using the nitrogen adsorption test, the test results of micropore probing is still heuristic to some extent. In addition, combined with the BET theory, the BET surface area can also be obtained from nitrogen ...
Test coal samples were obtained from the face of coal blocks in Shanxi Province. This sample's dimensions were determined using a vernier caliper, which is approximately 100 mm × 50 mm × 50 mm, and the weight was measured using an electronic balance. Figure1illustrates the sample ...
