Abstract:In view of the difficulties of updating 3D geological model caused by multi-person collaboration,tedious measurement process and low efficiency in traditional traverse survey of working face,a dynamic revision technology of geological model based on coal-rock boundary geological recording device is proposed.Firstly,the geological model of the working face is constructed by collecting the relevant geophysical exploration,drilling,supplementary exploration data and roadway development information.Then the geological recording device is used to measure the coal rock boundary at the current mining position of the fully mechanized mining face,and the coordinates of the coal rock boundary point on the roof and floor of the coal seam are obtained.Finally,the measured coal-rock boundary point data are imported into the initial geological model,and dynamic model correction is achieved through technologies such as topological relationship analysis,spatial data interpolation,and TIN model reconstruction,thereby achieving"transparency"of the geological body within a certain range ahead of the current mining position.Application of this technology in the fully mechanized mining face of Jinfeng Coal Mine demonstrates its ability to satisfy the engineering requirements for adaptive coal cutting in intelligent mining,providing core geological data support for efficient and precise mining at the working face.
