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.
