Abstract

Activities mining can make the impact to a land, so that needs to be done reclamation in an effort toincrease the quality of land and improvement of the conditions the former land of the mine. In thiseffort to ensure and provide an assessment and protecting the environment, after the mining activitiesPT Pipit Mutiara Jaya conducted activities arrangement and the land use former mine by means ofrevegetasi. The assessment of the level success reclamation use Permen ESDM No.7 2014 On theimplementation of the extension of reclamation and mine close in business activities minerals and coalmining the total value of Pit 1 is 67,82. So that the implementation of reclamation on land formermining PT Pipit Mutiara Jaya fall into the criteria and, namely result for reclamation received with aneed to to the repair Until it reaches > 80 that is good (in the reclamation acceptable).

Abstract

Coal mining by PT. Tambang Bukit Tambi uses an open pit mining system where one of the factors that can affect mining is water that entering the mining area, so water control must be carried out, one of the ways is by using mine dewatering system. The purpose of this study is 1) To know the debit of water entering the mining area. 2) To design a pumping plan 3) To create an ideal sump design for handling water that entering the mining area. Based on the research, the daily discharge is 32,243.36 m3 / day where the water discharge that can be released by 2 Kenflo XA 125 / 40B pumps is 640 m3 / hour in 50.38 hours and the water control effort is made a sump that must accommodate water amounting to 19,427.26 m3 and after the calculation is obtained a trapezoid-shaped sump design with size length and surface width of 63.7 m, length and width of the base of the sum of 60.9 m and depth of 5 meters.
