| description | Along with the gradual normalization of coordinated cross-mining of multiple mineral resources, the safety situation of natural gas wells has become increasingly serious. Taking coal-gas cross-mining in the Ordos Basin as the research object, this paper proposed an anti-collision early warning method based on vibration wave monitoring prevent the occurrence of collision accidents between roadheader and gas well. Through the steel pipe percussion vibration test and coal mine excavation vibration test, the attenuation law of vibration waves in the steel pipe and coal rock is studied, and the formula for calculating the distance from the roadheader to the natural gas well is deduced according to the vibration attenuation law. The results show that the attenuation coefficients of vibration waves in steel pipes and coal rocks are different, but the attenuation laws are basically the same, both conforming to the exponential attenuation law, with the vibration waves first decaying rapidly and then slowly. It provides a reference for the realization of surface monitoring of the distance from the roadheader to the natural gas well, preventing collision and predicting early warning. |
