After more than one year of experiments, Guizhou Province has made important breakthroughs in coal exploration technology. A new technology called “seismic exploration†has matured and applied.
According to Yi Tongsheng, chief engineer of Guizhou Coalfield Geology Bureau, this new technology can determine the structure and trend of underground coal seams by connecting the seismic wave reflections generated by shooting on the ground and then connecting one point and one point. Its thickness and reserves. The coal seam with a thickness of 0.8 m can be detected on the instrument, and the coal seam with a thickness of 1.5 m or more can be accurately and accurately reacted. Moreover, faults with a coal seam width of 10 m and a drop of 3 to 5 m can be ascertained. This is not possible with traditional exploration.
In the past, geological exploration in coalfields in Guizhou Province has always used drilling, logging, laboratory testing and other methods. Due to the complex and variable geological structure in Guizhou, even if the exploration is intensive, the hole spacing can only reach 500 meters, and whether the coal seam is continuous within 500 meters. It is impossible to find out continuously, and it can only detect faults with a drop of more than 30 meters. “Seismic exploration is not only accurate, but at least half the time in comparison to traditional exploration.â€
It is reported that the use of seismic and electrical exploration for coal seam continuity tracking and coal seam thickness change trend prediction and prediction of rich water area can provide information management solutions and detailed for coal mine face layout, gas and mine water prevention. Geological information has greatly improved the economic benefits of coal mining enterprises and effectively controlled the occurrence of safety accidents such as water penetration.
