三维地震勘探技术在单侯井田中的应用
|
摘要
三维地震勘探是一种简便、可靠、经济、高效的勘探方法。在研究单侯煤矿勘探区地质构造特征的基础上,对勘探区进行了三维地震补充勘探,并对勘探成果进行验证分析。此次三维地震勘探后取得了大量地质资料,与三维地震勘探前相比,解释的50条断层均为新发现断层,本次三维地震勘探不仅查清了各煤层的赋存状态及奥灰的起伏情况,而且对主要煤层的厚度变化趋势进行了分析研究,为采掘设计、工程施工和安全生产提供了可靠的地质依据,对煤矿的安全生产起着重要作用。
3D seismic prospecting is a simple,reliable economic and efficient exploration method.It make the 3D seismic supplementary geological exploratory in exploration area,and the verification and analysis for exploration results on the basis of Studying geological structure characteristics of exploration area,this three-dimensional earthquake exploration achieved fruitful geological results compared with before,the 50 items interpretation of the faultage are all the new findings.The 3D seismic exploration not only checked out of each coal seam occurrence condition and the Ordovicion limestone’s ups and downs,as well made analytical investigation for the main coal seam thickness variation trend.It provides a reliable geological basis to mining design,engineering construction and safety production,playing a very important role for coal mine safety production.
