Sedangkan, tujuan dari kegiatan pemboran Meanwhile, the purpose of the infill drilling infill adalah untuk menambah keyakinan activity is to increase the confidence of the batas penyebaran lateral dari seam-seam lateral spreading limit of potential seams that potensial yang mengalami pinchout, has been pinch out, increase confidence in menambah keyakinan kemenerusan serta continuity and determine the thickness of the mengetahui ketebalan lapisan ke arah layer towards the down dip which is indicated downdip yang terindikasi mengalami to be thinning to the planned lower pit limit, penipisan hingga rencana batas bawah pit, and maximize the mineable reserve of serta memaksimalkan mineable reserve potential seams, and validate the update of seam-seam potensial, dan mem-validasi the Geology model from the update of adding update model Geologi dari pembaruan infill drilling data penambahan data pemboran infill. Pemboran infill pada area pit AB Infill drilling in the pit AB area is planned to be direncanakan dilakukan sebanyak 13 titik bor carried out as many 13 boreholes with a total dengan total meter yang diperlukan adalah required meter of 1000 meters. The work is sebanyak 1000 meter. Pekerjaan tersebut planned to be carried out using a minimum of rencananya akan dikerjakan dengan 2 units of Jacro 300 rigs or the like. This infill menggunakan minimal 2-unit rig tipe Jacro drilling project will be carried out using the 300 atau yang sejenis. Proyek pemboran infill vertical touch coring drilling method and ini akan dilakukan dengan menggunakan equipped with geophysical logging up to the metode pemboran touch coring vertikal dan drilling depth target. dilengkapi dengan geophysical logging sampai dengan target kedalaman pemboran.
