摘要： A multi-stage combustion impact wave coal mass cracking and heat injection alternating intensified gas extracting method is provided. A large amount of N2 or CO2 is injected into a drill hole by a heat injection and gas injection extracting pipe and by a high-pressure gas cylinder and a reducing valve, then a certain amount of methane and dry air are injected into a high-temperature and high-pressure combustion chamber by the high-pressure gas cylinder and the reducing valve, to be mixed and combusted to form high-temperature and high-pressure impact wave. High-temperature vapour is injected into the drill holes by the heat injection and gas injection extracting pipe to promote desorption of the coal masses.

摘要： The present invention discloses a combined automatic anti-explosion method for a gas drainage pipeline, comprising specific steps of: preparation of an anti-explosion installation piping; connection of the installation piping and the gas drainage pipeline; assembly of a porous foam material and an automatic control valve; installation of an automatic powder-spraying device and a signal analyzer; installation of a temperature sensor and a pressure sensor; and signal processing and automatic anti-explosion. According to the present invention, the porous foam material is located in a bottom groove of an arched pipeline when no gas explosion occurs in the gas drainage pipeline, without affecting the extraction effect of the gas drainage pipeline. If a gas explosion occurs, the present invention blocks the pipeline with the porous foam material due to its fire resistance and pressure reduction performances, and the automatic powder-spraying device sprays a certain amount of a dry powder explosion suppressant to reduce the explosion overpressure generated in the gas explosion process and isolate the propagation of flame, so that the safety performance of the gas drainage pipeline is ensured, and thus the safety production of coal mines can be ensured.

摘要： A method for collecting gas from subterranean formations having a plurality of spaced-apart coal seams containing methane gas includes the steps of drilling a shaft from the earth's surface to a depth sufficient to intersect a plurality of seams containing gas and thereunder to create a sump. A plurality of generally horizontal holes are drilled from the shaft into selected seams and gases collected from the boreholes and conducted through the shafts to the earth's surface. Apparatus, including a movable and rotatable platform, is lowered to a position adjacent the coal seam containing methane gas and an array of generally horizontal holes drilled from the platform into each of the coal seams from which methane gas is to be collected. Liners are inserted in each of the boreholes and interconnected through a riser for conducting the methane gas to the earth's surface. The method and apparatus of the invention enables the collection of methane gas from spaced-apart subterranean seams having narrow thickness.
