Coal Geology & Exploration
In order to study the feasibility of the fault detection by transmitting channel wave in thin alternating coal seams of southwestern region, a representative area was selected, and a coal mine in Panzhihua Coal Industry Group was selected as the research object. A three-dimensional geological model with three alternating coal seams containing three partings, three partings and faults and without parting was established based on actual geological data. Through the forward simulation and analysis of the characteristics of the wave field and the frequency dispersion of the channel waves of the three dimensional elastic wave, the validity of the amplitude …
