; Изобретение относитс к горному делу и может быть использовано при разработке угольных пластов, склонных к внезапным выбросам угл и газа .; The invention relates to mining and can be used in the development of coal seams prone to sudden emissions of coal and gas.
Известен способ определени выбросоопасности угольных пластов, включающий определение газосодержани угл в лабораторных услови х при существующем в пласте давлени газа, определение эффективной газоносности по разности газосодержаний угл при давлении газа в массиве и при атмосферном давлении в горной выработке, по которой производитс определение выбросоопасности угольного пласта l.A known method for determining the outburst hazard of coal seams includes determining the gas content of coal in the laboratory at the gas pressure existing in the reservoir, determining the effective gas content from the coal gas content at the gas pressure in the massif and at atmospheric pressure in the mine workings, which determine the outburst hazard of the coal seam l .
Недостатком способа вл етс определение газосодержани угл в лабораторных услови х без учета напр женного состо ни пласта и горногеологических условий.The disadvantage of this method is the determination of coal gas content in laboratory conditions without taking into account the stress state of the formation and geological conditions.
Известен также способ оценки выбросоопасности угольного пласта.There is also known a method for estimating the outburst hazard of a coal seam.
основанный на определении его газоносности , включающий поинтервальное бурение шпуров, герметизацию их усть , измерение на каждом интервале шпура объема газа, выделившегос при бурении и очистке шпура,.измерение газовыделени из стенок шпура .соответственно перед и после бурени интервала шпура, определение выхода буровой мелочи, времени буре10 ни и очистки одного интервала шпура 2.based on the determination of its gas content, including interval drilling of holes, sealing their mouth, measuring the volume of gas released during drilling and cleaning the hole at each interval of the hole, measuring gas release from the hole of the hole, respectively, before and after drilling the hole interval, determining the output of the drill, the time of the drill10 and the cleaning of one hole interval 2.
Недостатком данного способа вл етс его относительно невысока точ15 ность установлени выбросоопасности угольного пласта, поскольку при отборе штыба дл определени остаточной газоносности лабораторным способом тер етс значительна часть The disadvantage of this method is its relatively low accuracy of determining the outburst hazard of a coal seam, since a significant part of the process is lost during the screening for determining residual gas content in the laboratory.
