Abstract

Rainfall is one of the factors that has a large influence on the mining area. Rainfall with a large frequency and long duration will certainly result in production failure that can disrupt mining activities. This research was carried out aimed to determine the effect of rainfall on the production of coal conveyance. The research method used in this research activity is by combining the planned data and actual data and rainfall data carried out starting from literature studies, field observations, data collection, and data processing. The study was conducted on February 11, 2019 until March 29, 2019. The evaluation planned in this study was to find out the production plan was calculated at 446,700.78 tons / month. Then the actual amount of production in coal mining at the study site was obtained at 279,462.30 tons in February 2019 and 418,564.55 tons in March 2019. Rainfall has a high level of intensity and rainy hours resulting in a decrease in the production of coal hauling equipment not achieving production targets. The decline in production can only be achieved by coal production of 2896.11 tons / day when the rain has a high intensity of 39,70 mm in February, and also a decrease in coal production in March which is 7954,95 tons / day with intensity the high is 37,40 mm.
