The invention discloses a gas detection method for non-coal gas tunnel engineering. The gas detection method comprises the steps of tunnel sliding rail installation, gas detection mechanism installation, gas exhaust device installation, gas conveying pipeline arrangement and gas detection exhaust treatment. According to the invention, not only can the non-coal gas tunnel be continuously detected, but also the gas at the leakage point can be absorbed and exhausted when the gas leakage position is found, the content of the gas in the tunnel is reduced, the safety is improved, the gas leakage point can be sent to the background control center, timely treatment is facilitated, the blocked point is rechecked, and the working efficiency is improved. And the detection efficiency is greatly improved.
Description
Technical field [0001] The present invention relates to a gas detection method for non-coal gas tunnel engineering. Background [0002] Traffic tunnel gas can be divided into coal bed methane and non-coal bed methane, non-coal bed gas tunnel exists in the coal formation away from the coal seam of the non-coal formation or non-coal formation geological weight of toxic and harmful combustible natural gas types, generally in the free state. In the tunnel engineering, it has the characteristics of the outflow location, the outflow pressure and the uncertainty of the outflow volume, and its combustion and explosion disasters have the characteristics of low probability but extremely high danger. [0003] The gas detection method in the existing technology can generally only detect and alarm the gas in the tunnel, and cannot reduce the content of gas in the tunnel in time, so it is easy to cause safety problems for the construction personnel in the tunnel.
