Exploration of coal seams intruded by magmatic body using seismic attribute technology

reduces the coal quality, causes the waste of coal resources, and
brings hidden dangers to the safe production of the coal mine. Thus,
detecting the parts of coal seams intruded by magmatic bodies is
extremely important. This paper describes the mechanism of
intrusion of a magmatic body into a coal seam and introduces the key
steps of Seismic Attribute Technology. After the intrusion of a coal
seam by magmatic bodies, seismic attributes such as frequency
bandwidth, main frequency-band energy, average instantaneous
phase, and root mean square (RMS) amplitude change significantly.
Taking the testing project of Haizi Coal Mine in Anhui Province,
China, as an example, the accuracy of using Seismic Attribute
Technology for detecting the range of magmatic body intrusion into
coal seams was confirmed.
