Gas drainage design for extraction areas in highly gassy and outburst-hazardous coal seams in Karaganda Basin

Intensification of coal mining and complication of geological conditions of mining alongside with the reducing number of production faces necessitates enhancement of safety performance in extraction areas. One of the main conditions in this regard is the correct prediction of methane content in the production face area. This issue has been a subject of many recent researches but the effective standards yet use relations set over 40 years ago on the basis of the statistic approach neglecting the coal–methane–water system behavior. This study aims to adjust application ranges of the actual methods of methane content prediction, to identify major problems and to develop improvement activities toward the mine air safety. The article describes the methane content research in the extraction panel in the east wing of Kazakhstanskaya Mine, which is the super outburst-hazardous coal seam. It is shown that the difference of the calculated and actual methane contents exceeds 100%, which is connected in many ways with the slicing technology of mining and with the understated estimates of natural gas content of the test coal seam. For another thing, efficiency of gas drainage in a mined-out area greatly depends on pre-drainage treatment of coal seams.

Keywords: gas content, load, gas emission, gas drainage, efficiency, operating coal seam, mined-out areas, outbursts, prediction.
