Apr 27, 2021 Coal is an essential commodity used as fuel for energy and raw material in the production of metals and chemicals. As of 2016, coal provided about a quarter of the worlds primary energy and two-fifths of electricity usage. Proper quality control is imperative for producers to minimize costs, improve operations, and reduce emissions.
This paper addresses the quality control problem faced by a coal mine of satisfying a specified minimum net calorific value NCV requirement for the coal loaded at an export harbour, by means of a control strategy on the gross calorific value GCV at the mines wash-plant. From the NCVGCV relationship a formula for the target mean GCV at the wash-plant is derived. This takes into account ...

The main goal of coal quality control in lignite mines is to supply coal to power plants within certain quality constraints. Coal properties can affect the efficiency, reliability, and availability of both the boiler and the emission control units. This paper presents a new based integrated mine
Essentially, the control of dust deposition on its own is not sufficient, on its own, for air quality management control. Dust types which are a particular nuisance originate from coal and iron ore mining. These cause discolouration, and in some cases permanent damage. In
A sound roof control plan is essential for controlling the roof, face and ribs, including coal or rock bursts in underground coal mines. Each mine operator is required by 30 CFR 75.220 a 1 to develop and follow a roof control plan, approved by the District Manager, that is suitable to the prevailing geological conditions and the mining

Using these values, ABA is a good tool to assess overburden quality before surface mining and to predict post-mining drainage quality after mining. The interpretation from ABA values was correct in 50 out of 52 cases 96, excluding the four anomalous sites, which had acid water for reasons other than overburden quality.
