Abstract
1. Способ ведения взрывных работ в шахтах, опасных по нефтегазоносности, включающий проектирование буровзрывных работ (БВР) на основе геологической информации, бурение, заряжание и забойку шпуров, монтаж электровзрывной сети и взрывание, отличающийся тем, что при проектировании БВР на планы горных работ наносят границы зон, опасных по газодинамическим явлениям, и на расстоянии 1-3 метра до границы опасной зоны и в ее пределах бурение забоя выработки осуществляют укороченными, не более 1,4-1,6 м, шпурами. ! 2. Способ ведения взрывных работ в шахтах опасных по нефтегазоносности, включающем проектирование БВР на основе геологической информации, бурение, заряжание и забойку шпуров, монтаж электровзрывной сети и взрывание, отличающийся тем, что при проектировании БВР выделяют потенциально взрывоопасный участок и на расстоянии 1-3 м до границы опасной зоны и в ее пределах бурение и взрывание забоя выполняют двухфазным (в два этапа). ! 3. Способ по п.2, отличающийся тем, что при ведении взрывных работ в горизонтальных выработках первоначально бурятся и взрываются шпуры верхней части выработки, на втором этапе - нижней части выработки, а при ведении взрывных работ в вертикальных выработках сначала заряжают и взрывают центр ствола (вруб), а на втором этапе взрывают шпуровые заряды по контуру забоя. 1. The method of blasting in mines hazardous to oil and gas content, including the design of drilling and blasting (BWR) based on geological information, drilling, loading and jamming holes, installing an electric blast network and blasting, characterized in that when designing the blasting plan, they apply to mining plans the boundaries of zones dangerous by gas-dynamic phenomena, and at a distance of 1-3 meters to the border of the dangerous zone and within it, drilling the bottom of the mine is carried out with shortened, not more than 1.4-1.6 m, holes. ! 2. The method of blasting in mines hazardous for oil and gas, including the design of explosive blasting based on geological information, drilling, loading and jamming holes, installing an electric blast network and blasting, characterized in that when designing blasting explosives, a potentially explosive area is isolated at a distance of 1-3 m to the border of the danger zone and within it, the drilling and blasting of the face are performed in two phases (in two stages). ! 3. The method according to claim 2, characterized in that when blasting in horizontal workings, the holes of the upper part of the workout are drilled and exploded, in the second stage, the bottom of the workout, and when blasting in vertical workings, the center of the barrel is first charged and detonated (cut), and at the second stage, blast holes are blown along the face contour.
