“…There are 14 major faults identified in the minefield which have NEE and NNE strike directions, including the Goulifeng normal fault, and the Gaogou thrust fault. The Goulifeng normal fault and Gaogou thrust fault have the largest extension lengths in the wellfield, and the Goulifeng normal fault is located on the west side of the wellfield, cutting into the Baishishan anticline and Lingwushan syncline with a drop of about 150 m. The extension length of the wellfield is 5500 m. The Gaogou thrust fault is located in the eastern part of the wellfield near the Baishishan anticline, with a drop of about 40 m, and the extension length of the wellfield is 2070 m. The rest of the faults are located on the eastern side of the Goulifeng normal fault, with a drop of 3-10 m, and their extension lengths are less than 1000 m [34]. In addition to this, there are 352 small faults catalogued in the roadway of the No.…”

The parameters of coalbed methane reservoirs have large differences, and the precise values cannot represent the resource and production characteristics of the whole block. In order to address these problems, an index system for evaluating the production potential of coalbed methane blocks was constructed, the weights of evaluation parameters were determined, and a model for the preferential selection of coalbed methane blocks based on the subjective–objective combination of weights method was established. The main coal seams (No. 2-1 and No. 4-2) of the Pingdingshan-Shoushan I Mine Block were taken as the research objects to rank the development potential of CBM blocks in a preferential way. The results show that the six resource and production parameters of No. 2-1 coal are gas content, top and bottom rock properties, coal seam thickness, coal seam depth, coal body structure, and tectonic conditions, in descending order of importance, and the parameters of No. 4-2 coal are gas content, coal body structure, coal seam thickness, top and bottom rock properties, coal seam depth, and tectonic conditions, in descending order of importance. It is predicted that the favorable CBM gas development sweet spot areas of the No. 2-1 coal seam and No. 4-2 coal seam will be located along the exploration wells W15–W29 and W31, respectively. This paper aims to make a multi-dimensional and more comprehensive evaluation of coalbed methane mining potential in the Shoushan I mine, and provide a technical basis for the next step of coalbed methane mining in the study area.
