煤田三维地震勘探技术首次应用于西部戈壁地区,针对勘探区浅表砂砾层干燥疏松和煤层埋深及其倾角变化大的不利因素,首先,通过试验选取适合本区的激发与接收因素,并确定合理的观测系统及施工方法。其次,对获得的信噪比较高的原始资料,做好资料处理与解释。通过采取一系列有效技术措施,查明了勘探区褶曲、断层构造特征,控制了主要煤层的空间分布范围。取得的这些地质成果,将成为矿井建设和生产的可靠地质依据。
Coalfield three-dimensional seismic exploration technology for the first time applied to the western Gobi area, for the exploration area shallow superficial gravel dry loose and coal seam depth and dip angle of the unfavorable factors, first of all, by selecting the appropriate excitation and receiving factors in the area, and to determine Reasonable observation system and construction method. Second, do a good job of data processing and interpretation of the original materials with high SNR. Through a series of effective technical measures, the features of fold and fault in the exploration area have been identified, and the spatial distribution of the main coal seams has been controlled. These geological achievements obtained will become a reliable geological basis for mine construction and production.
