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.

Abstract

The purpose of mine dewatering system is to control runoff water that enters mine openings so that the mining process is not disturbed. The rainfall discharge (Q) is 0.0951 m³/second and the runoff discharge (Q) is 0.69 m³/second, making the total mining discharge entering the location 0.781 m³/second. The open channel design has dimensions of Channel wall slope (α) = 60°, Water depth (h) = 0.73 m, Channel depth (d) = 0.83 m, Channel base width (B) = 0.73 m, Surface width (b) = 1.57 m, Wet cross-sectional area of channel (A) = 0.92 m², and Channel wall length (a) = 0.97 m. The sedimentation pond has the following dimensions and compartments: Total length (l) = 104 m; width (b) = 8 m; depth (H) = 4 m; partition width = 4 m; partition depth = 4 m; partition length = 7 m. It consists of 3 compartments: conditioning compartment, separation between solids and mine water, and flow with an area of 277 m² per compartment. The sedimentation pond volume is 3094 m³ with a total area of 830 m². The results of the study obtained information that to control runoff water entering mine openings, a pond capacity as a settling site was needed of more than 3094 m³ with a maximum dredging time of settling pond particles that can be done once every 10 months.

Abstract

Wastewater pollution in mining areas often occurs and becomes a problem in the surrounding groundwater aquifer system. One of the efforts to determine the distribution of wastewater pollution is to calculate the discharge and volume of wastewater. In this study, an open channel in the form of a ditch or commonly referred to as a drainage system is carried out to determine the total water discharge entering the research location, design the dimensions of the sump and design the optimal cross-sectional dimensions of the ditch to overcome the discharge of water that comes out and pollutes the environment. The method used is to make an open channel in the form of a trapezoid to be used around the andesite rock mining site which then drains the mine water to the setlingpond. Efforts to drain the water that has entered the main sump (mine dewatering system) are carried out by making wells, after which the waste water is channeled into the settling pond using a pump. From the results of the study, information was obtained that the total water discharge entering the sump was 235,175 m so that the volume of the sump made was 300 m with dimensions of top area: 20m x 10m, bottom area: 10m x 10m, with a depth of 2m for total water discharge for ditches. 0.0237 m so that the volume of the trench made is 0.228 m.

Abstract

The presence of water in mining activities is common, especially in tropical areas that have high rainfall, such as the research location at PT ANTAM Maluku Utara at the Moronopo Site. While the sump maintenance needs to be considered so that the sump can accommodate the incoming discharge. The purpose of this research is to calculate the total discharge entering the mine and to design the dimensions of the sump according to the incoming water discharge. The research method used is the Gumbel method starting from the analysis of rainfall data at the research location starting in 2004-2013 and then continuing with 2019-2020 data, the planned rainfall value is 96.56 mm/day, rainfall intensity is 15.63 mm/day hours with a rain return period of 25 years and a hydrological risk of 18.46 % and the total inflow of mine water is 17,556 m3/hour. After calculating the sump capacity in the Danis 2 area, it still has not accommodated the incoming discharge with the remaining unaccommodated discharge of 2,319.1 m3/hour.

Abstract

This research was conducted at PT. Antareja Mahada Makmur on the mining concession owned by PT. Multi Harapan Utama which is located in Sungai Payang Village, Loa Kulu District, Kutai Kartanegara Regency, East Kalimantan Province. The rainfall data used is for 10 years (2012-2021) which comes from the Dewatering Mining Engineering Department. Data analysis was performed by statistically calculating rainfall data using the Gumbell method to obtain the planned rainfall value. Then the calculation of runoff water discharge is carried out to analyze the existing mine drainage system by comparing the actual conditions and the results of technical calculations. Based on the results of the research for rainfall data for 2012 – 2021, Gumbell's calculations plan to collect rainfall of 94.23 mm/day, rainfall intensity of 14.74 mm/hour with a return period of 5 years and a hydrological risk of 89.26%. The total for the Gumbell method runoff discharge is obtained for runoff water entering the Sump 90 Besar of 2.19 m3/second, runoff water entering the Sump 90 Lorong of 3.03 m3/second, and for water discharge runoff that goes into Sump 100 is 3.68 m3/second. The three open channels in the form of trapezoids and culverts have met the theoretical calculation dimensions, with dimensions that are still able to accommodate and drain runoff water discharge. For three dimensions of the actual sump that is currently smaller than the theoretical calculation of the well volume, the sump capacity calculation obtained a recommended sump volume of 47,045 m3 for a 100 sump, for a sump 90 lorong of 43,012 m3, and for a sump 90 besar of 40,635 m3, with recommended dimension improvements. The operating speed of the pump needs to be increased for the Multiflow  MF - 420 pump on a sump 90 lorong from 1159 m3/hour to 1224 m3/hour with an efficiency of 65%, Multiflow  MF - 420 pump on a sump 90 besar from 1123 m3/hour to 1269 m3/hour with an efficiency of  70 %, for the Multiflow  MF - 420 pump at sump 100 from 1282 m3/hour to 1584 m3/hour with an efficiency of 65%.
