Изобретение относитс к горной промьшшенности и может быть использовано при разработке выбросоопасньгх угольных пластов.The invention relates to the mining industry and can be used in the development of outburst coal seams.
Целью изобретени вл етс повьппе- ние надежности и точности вы влени опасных участков,The aim of the invention is to increase the reliability and accuracy of detection of hazardous areas,
Способ осуществл ют следующим образом .The method is carried out as follows.
Перед проведением горной выработки известными способами определ ют геотермическую темг1ературу исследуемого массива горных пород. Из забо проводимой горной выработки бур т скважину и с помощью датчиков измер ют температуру в ней.Before carrying out mining operations, the geothermal temperature of the studied rock massif is determined by known methods. From the bottom of the mining operation, the well is drilled and the temperature in it is measured using sensors.
Определ ют разность между температурой в скважине и геотермической температурой. Затем эту скважину гер- метизируют и одновременно с проведением горной выработки производ т измерение температуры в загерметизированной скважине и определе ше разности между этой и геотермической темпе- ратурами.The difference between the temperature in the well and the geothermal temperature is determined. Then this well is sealed and, at the same time as the mine development is carried out, the temperature in the sealed well is measured and the difference between this and geothermal temperature is determined.

разность температур) и разрушени угл в загерметизированной скважине (положительна разность температур), Одновременное наличие указанных разностей температур на любом участке угольного пласта свидетельствует о том, что зтот участок вл етс опасным по газодинамическим влениемtemperature difference) and coal destruction in a sealed well (positive temperature difference). The simultaneous presence of these temperature differences at any part of the coal seam indicates that this area is dangerous for gas-dynamic phenomena.
