利用三维地震资料研究夹河煤矿煤层厚度

Study on Coal Thickness in Jiahe Coal Mine by Using 3D Seismic Datas

摘要:

夹河煤矿位于徐州市西北部，设计生产能力为140万t/a，新构造活动不强，构造稳定性较好。通过对矿区地震特征、煤储层特征分析，认为区内煤层稳定且储量大，该文以夹河煤矿为例，利用常规解释方法和地震属性参数技术解释了2煤层的煤层厚度，分析了地震属性剖面及煤层厚度图的成图方法，从而找出煤层厚度的变化规律，取得了较好的地质效果，为矿井采掘提供高精度地震勘探资料。

Abstract:

Jiahe coal mine locates in the northwest of Xuzhou city. Its designed capacity is 1.4 millon tons every year. New structural activities are not strong and structures are stable. Through analysis on seismic characteristics and coal reservoir characteristics in mining area, it is considered that coal layers in the area are stable with large reserve. In this paper, taking Jiahe coal mine as an example, by using conventional interpretation method and seismic attribute technology, the thickness of No.2 coal strata is explained, seismic attribute sections and method for making the map of coal strat thickness, and the change law of coal seam thickness have been found out. It has achieved good geological effect, and provide seismic prospecting information with high precision in coal extraction.
