Abstract:
Mine transient electromagnetic method,mine direct current method,mine rayleigh wave method,mine reflected wave method four kinds of mine advanced detection technology are adopted to forecast water disaster in coal mine heading face.By the mine data acquisition,processing and inverse calculation,visualization graph is formed,and use it explain range and location characteristic of the mine water-logged stratum and structural,so as to build built a set technology method for mine geophysical dynamic monitoring water disaster in coal mine tunneling process.Result indicates that mine transient electromagnetic method may detect heading face water-contained of positive front,front roof,front floor and front sidewall;mine direct current method may detect heading face water-contained of positive front;mine rayleigh wave method(or mine reflected wave method) may detect front structure and goaf boundaries.
