Technical Field

[0001] The present invention belongs to the technical field of coal resource exploration, and in particular relates to a method for processing information of seismic wave exploration of coal while digging, and also relates to a system for processing information of seismic wave exploration of coal while digging. Background Art

[0002] Seismic exploration technology has made great contributions to my country's coalfield exploration. Especially in recent years, the country has attached increasing importance to seismic exploration technology. Through the joint efforts of seismic exploration technicians, my country's coalfield seismic exploration technology has also made great progress. Moreover, with the improvement of various instrument manufacturing technologies and information remote sensing technologies, seismic exploration instruments are constantly developing in the direction of telemetry and remote control, high sampling rate, and multi-channel collection. Seismic exploration acquisition, processing, and interpretation technologies have been continuously improved.

[0003] Over the years, geological exploration workers have studied many methods to accurately predict coal seam thickness, but the results are not very good and the error range is too large. Sometimes a single attribute, such as the maximum amplitude attribute feature, is used for estimation, which results in a large error. Some software is also used for estimation, but the procedures are complex and the calculation cycle is long. It takes about a month to calculate the result, which takes a long time and a large amount of calculation. In addition, the data results are somewhat disorganized and the accuracy is not high.

[0004] In order to ensure the safety of mine production and guide coal mine production to be carried out safely, efficiently and orderly, coal mine geological technical management work generally requires all coal mining areas to conduct three-dimensional seismic exploration. In its geological tasks, the mine generally requires an explanation for the changes in its coal seam thickness, which is also a difficult problem in three-dimensional seismic interpretation work. Traditional methods will inevitably fail to meet actual work needs.

[0005] In order to solve the above problems, the present application proposes a method and system for processing information of seismic wave exploration during coal excavation. Summary of the invention
