Abstract:By using integrated exploration methods, such as surface geophysical exploration method, drilling and underground exploration Lane method, and the combination of exploration and drilling method, supplemented exploration was carried out in deep part of Lucun coal well, and the former geological information of this coal well were contrasted and analyzed. It is found that within the scope of -400~-1300m in this well, It not only existed the upper part of Taiyuan formation which was regarded eroded and missed in the past, but also preserved complete Shanxi formation. In the newly discovered strata, five regional coal layers have been found. It will increase the reserves of coal mine, extended service life of coal wells, and fill the information gaps of the upper part of Taiyuan formation and coal-bearing strata in Shanxi formation.
