Abstract

Nickel is one of the metals needed by humans. In general, nickel can be formed primarily or secondarily, known as nickel laterite. Nickel deposits in Indonesia are only found in the form of nickel laterite. The parent rock of nickel laterite deposits is ultrabasic rock, especially from the types of harzburgite, dunite, and other peridotites. The data collection technique used is to take data related to the research, both primary and secondary data. Primary data includes outcrop data (megascopic description) at the research location, exploration drill data to determine the thickness of the nickel laterite layer and the content of its elements and rock sample data for petrographic thin section analysis. Sampling was carried out in block A. While secondary data includes data on the general condition of the company, and a map of the research location. 1. The original rock analyzed petrographically is serpentinezed harzburgite. The minerals contained are orthopyroxene, olivine, clinopyroxene, and opaque minerals. The weathering level of the nickel laterite profile in the limonite zone is higher than the saprolite zone because in the saprolite zone most of the rocks are small in size and the original rocks affect the nickel laterite profile that is formed, but are still supported by other factors, namely topography, climate, geological structure, vegetation and time.

Abstract

The problem that is often faced in mining activities in open pit mines is high rainfall that can hamper mining operations. Mine Dewatering is a handling of mine water problems by removing water that has entered the mining area (by utilizing differences in height and gravitational force) through drainage channels to temporary storage ponds (sump). This system is commonly applied for handling runoff from rainwater. The purpose of this study is to find out the volume of water entering the mining front, analyze the ideal sump volume to hold runoff water and analyze the ability and duration of pumping to slice water that is in the sump. The average rainfall obtained from data for 2019-2022 is 81 mm/day. The calculation of planned rainfall is determined using a gumble distribution, the calculation of planned rainfall based on the repeat period over 2 years is 201,658 mm/day. Based on the results of the study, the average rain time was 11.97 hours, rainfall intensity was 6,572 mm/hour, runoff coefficient was 0.9 and the rain catchment area was 692,000 m2. So that the runoff water discharge that enters the sump is 4,093.04 m3/hour, the total volume of water entering the sump is 98,233 m3/day. The ideal sump volume to hold runoff water is 71,813.36 m3. The pumping discharge is 1,841.62 m3/hour, the length of sump drying time with an estimated pumping time of 20 hours/day is 9 days.
