地震勘探在准东煤田大井矿区的应用

随着西部煤炭资源勘探程度的进展，地震勘探已在准格尔盆地东缘大面积展开。为满足新疆准东煤田奇台县大井矿区开发和建设年产2000万t大型矿井的需要，对新疆准东煤田奇台县大井矿区三井田进行勘探工作，为矿井建设可行性研究和初步设计提供地质资料。根据矿井开拓方案，在勘查区的先期开采地段采用三维地震勘探方法查明构造和煤层的赋存状况，其他地段采用二维地震勘探方法控制。经钻孔验证,取得良好效果。

Application of Seismic Exploration in Dajing Mining Area of Zhundong Coalfield

Accompanying with development of coal resources exploration in western China, seismic exploration has been carried out in east margin of Zhungeer basin. In order to meet the development and construction needs of a large coal mine with an annual output of 20000000 tons in Dajing mining area of Qitai county in Zhungeer coalfield in Xinjiang province, exploration work of three coal wells have been carried out in order to provide geological data for the feasibility study and preliminary design and construction of the mine. According to the development plan, distribution of structures and occurrence condition of coal have been identified by using 3D seismic exploration method in the exploration area, while 2D seismic exploration method is used in other areas. It has good result verified by drilling datas.
