The invention, which relates to the field of methane sensors, discloses a laser methane sensor for a coal mine pipeline. The laser methane sensor comprises a housing and a main probe body. One part ofthe main probe body is arranged in the housing; and the main probe body can be arranged at the bottom of the housing by means of moving up and down. A buffer body and a buffer layer which are used for protecting the main probe body are arranged in the housing; the buffer body is at least provided with a buffer part abutted against the top of the main probe body; and the buffer layer is arranged in a gap between the inner bottom wall of the housing and the top of the main probe body. According to the methane sensor arranged in the main probe body, the buffer body and the buffer layer for protecting the main probe body are arranged in the housing, so that the laser methane sensor can be protected when colliding with a pipeline and thus a problem of inaccurate measuring data due to collisionis solved; and because the buffer body is provided with a first buffer part and a second buffer part which are arranged in a crossed mode, the buffer effect is improved and the laser methane sensor is better protected.
Description
technical field [0001] The invention relates to the field of methane sensors, in particular to a laser methane sensor for coal mine pipelines. Background technique [0002] With the deepening of mine mining depth and the increase of mining intensity, the amount of mine gas emission and the risk of coal and gas outbursts also increase accordingly; there are 348 high-gas and outburst mines in state-owned key coal mines, and the number of outbursts in recent years is 300 Several times / year, in accordance with the gas control policy of "drainage first, monitoring and monitoring, and wind to determine production" and the requirements of "reliable ventilation, drainage up to standard, effective monitoring, and management in place", carry out gas drainage for high-gas mines , monitoring, and treatment are particularly important; coal mine gas, also known as coalbed methane, is a hydrocarbon gas that exists in coal seams. Like natural gas, its main component is methane; the monitori...
