伊犁盆地伊北及伊南煤田勘查方法与实践

伊犁盆地煤矿资源储量丰富，前人陆续开展了不同程度的找煤工作。伊北、伊南煤田总体工作程度相对较低，且本区地层、构造条件复杂，勘查难度较大。地质+物探+钻探的煤矿综合勘查方法在本区勘查中面临较大挑战，创新改进工作方法为本区勘查工作取得成功的关键。在伊北伊南煤田勘查工作中，通过深入分析本区主要技术问题，不断创新勘查工作方法，在地层的重新厘定、二维地震勘探、钻探施工工艺及放射性评价等方面，实现了多项技术突破，解决了勘查过程中遇到的关键技术问题，取得了较好的找矿效果。同时，总结了该区找煤标志，建立了地震勘查和地球物理测井勘查模型，深化提升了煤矿勘查技术方法的一系列新认识、新成果，为煤矿勘查工作提供了有益借鉴。

Exploration method and practice of North and South Ili coalfield in Ili basin

Ili basin is rich in coal resources. Predecessors have carried out different degrees of coal exploration.The overall working degree of the north and south Yili coalfields is relatively low, and the stratigraphic and structural conditions in this area are complex, so the exploration is difficult.The comprehensive exploration methods of geology, geophysical exploration and drilling in coal mines are facing great challenges in this area.In the north and south of coalfield exploration, through in depth analysis of the major technical problems, through exploration and practice of innovative exploration method, the formation of reclassify, 2D seismic exploration and drilling construction process, and the evaluation of the radioactive, etc. achieved a number of technological breakthroughs, solves the key technical problems encountered in the process of exploration, has obtained the good ore prospecting effects.At the same time, a series of new understandings and achievements of coal exploration techniques and methods have been deepened and improved, which provide useful reference for coal exploration.
