Abstract:

This study aims to explore factors that contribute to mine plan achievement which further impact the coal discrepancy phenomenon or the variance between actual coal mined and planned. Secondly, the purpose is to develop a reliable monitoring tool for accurate implementation of mining activities at each stage, particularly for short-term periods such as daily and weekly plans. Data collection was carried out using empirical data collection of coal mined achievement from some pits, along with monthly data on the technical aspects contributing to this achievement. The coal discrepancy phenomenon is significantly influenced by four major factors, namely the accuracy of the geological model, change in mining sequence, operational loss and optimized mining. Implementing this new planning monitoring system has significantly increased compliance with planned mining sequences, facilitates the achievement of the final form of the mine in each period impacting short-term coal mined achievement. This research utilizes original digitalization in mine planning monitoring systems to optimize the mining sequence and improve the coal discrepancy phenomenon. It is critical since in coal mines, different stages of the mining process impact not only the amount of coal mined but also the aggregate properties of coal produced. It supports a resilient coal value chain, especially in the overburden removal phase, as an upstream area of coal mining.
