Beypazari Trona Mine is one of the two trona mines discovered in Turkey. Now the solution mining area has reached the boundary of the mining area. In order to maximize the recovery of trona resources under the standard conditions, it is necessary to arrange horizontal intersected well sets at the boundary of the mining area to mine the trona out. The geological conditions at the boundary of the mining area are complex with many folding and fault zones located in the study area of this paper. In the early drilling period, it is found that there are obvious geological anomalies in this area, such as pinching out, Vshape, or irregular and high dip angles of the primary mining layer. In view of these typical abnormal problems in drilling of intersected well sets at the boundary of the mining area, several technical measures, such as the casing section milling technology, directional drilling with azimuthal gamma tools and SmartMag targethitting systems, increasing the number of the exploration wells are adopted and all the problems have been resolved efficiently through these measures.
