Coal Geology & Exploration

Abstract

The intelligent accurate coal mining needs to construct the high-precision and transparent 3D geological model, and the seismic data interpretation integrated into the dynamic roadway data provide data support for the model. The geological model of roadway is established and forward modeling is carried out to analyze the difference of seismic characteristics caused by a roadway. Based on curvature attribute principle, various seismic curvature attributes were applied to seismic data interpretation, guide the roadway recognition in the seismic data. The coal seam 2 of CJT coalfield was selected as the research object, and the high-quality seismic data and various attribute bodies were obtained from 3D seismic exploration were used as the basic data.. Analysis found that the along-layer slices of the dip curvature attributes could depict completely the characteristics of the roadway anomalies showed the accurate position of the roadway, the clear boundary, had the higher precision. The research showed the feasibility and the effectiveness of the seismic dip curvature attribute technique for the recognition of the roadway. It provides a basis for detecting and identifying unknown roadway and the geological guarantee for the precise coal mining.
