Parametric modeling and arrangement of gas drainage in coal mines

It is necessary to justify gas drainage parameters in underground mining since the gas content of coal seams grows in deeper level mining while the gas recovery factor drops. The use of high-performance equipment in basic production processes in mines is only effective given the maximum pre-mine drainage of coal seams. The regulatory documents on operation safety in mines are examined. The review of the published research findings in this area shows that most studies focus on mining problems and on validation of gas drainage patterns. The issues connected with the gas drainage engineering in an extraction panel and the drainage process coordination with other process flows in mines lack attention. In this connection, the mechanism of operation-by-operation modeling of the gas drainage process parameters with regard to geological and geotechnical conditions, and to preparatory and actual production work is proposed. The model of the face output justification with regard to the coal seam gas emission rate is put forward. The calculation of the early gas drainage duration in an extraction panel versus its gas recovery factor is presented. It is proved that shear loader operation time can be increased due to early gas drainage. The requirement of integrated and coordinated arrangement of mine process flows in time and space is substantiated as this allows optimization at minimized time inputs. The recommended duration of the extraction panel gas drainage via holes drilled from roadways with regard to gas permeability factor of coal seams is determined.

Keywords: drainage patterns, early gas drainage, drainage factor, modeling process parameters, face output, limitation factors, process duration, process time management.
