一、必要性煤田地震勘探与石油地震勘探不同,它多以浅层为主,且多居向斜翼部,构造复杂,火成岩发育,勘探难度大;同时,随着机采程度的日益提高,对煤层的稳定性、连续性及煤层附近的小断层探明程度亦要求高 First, the necessity Coalfield seismic exploration and oil seismic exploration is different, it is mostly shallow, and more home to the syncline wing, complex structure, igneous rock development, exploration difficult; the same time, with the increasing degree of mechanical mining, The stability and continuity of coal seams, as well as the degree of detection of small faults near coal seams, are also demanding
