CARRYING MASSIF GAS POTENTIAL DISTRIBUTION AUTOMATED ESTIMATION METHODICAL GROUNDS
Journal Title: Вестник научного центра по безопасности работ в угольной промышленности - Year 2016, Vol 3, Issue
Abstract
Demands to the mine lease area computer geological survey database forming and operation are reviewed. The carrying massif gas potential automated evaluation method basics and numerical modeling results of their distribution along the area and depth of the mining lease and inside the extraction section are described. The algorithm of the calculation and examples of computer gas potential maps plotting are given, their variability was analyzed under different order of seams working out, including the layer system development, with different sizes of excavation pillars. The results are applicable as normative and methodological support in the planning and development of mining operations of coal mines, for rational planning of simultaneous coal and methane extraction, as well as for methane in ow dynamics forecast at coal extraction sections with different mining and geological conditions. The work is ful lled with nancial support of the Russian Academy of Sciences Siberian Branch complex program No. II.2 (0352-2015-0306).
