Abstract

Using C-ALS(Cavity-Auto scanning Laser System) to explore goaf and to establish a three-dimensional model in mining boundary of Anjialing surface mine could ensure the production safety. Three-dimensional laser scanner elevation is consistent that verified by drilling exploration goaf roof elevation. Coal seam is shallow in Anjialing district, small coal mining had a long history and the central of first mining area distributed small kiln mining area, these damaged severely the 4th and 9th coal seam. Goaf three-dimensional laser scanning technology as an advanced goaf measuring instruments had be widely used at home and abroad mine, using C-ALS for 1302 and 1316 level in Anjialing district carrying out goaf exploration, obtaining volume of goaf are 21138m3, and carrying out data processing and three-dimensional modeling for goaf, for subsequent safety evaluation of goaf, disaster warning and governance programs of goaf provide basic basis.
