Abstract

Morupule Coal Mine (MCM) classifies fines as coal particles that are less than 3.35 mm in size. Fines are one of the problems MCM is facing and have occasionally led to penalties from some customers. This paper quantifies the fines generated in MCM from the working face to the run-of-mine stockpile and its economic and environmental impacts. Data about the wash plant's production losses were collected through an examination of missed deadlines, stoppages due to tail-end blockages, and conveyor belt breakdowns using company reports. Data on coal dust concentrations were obtained from the mine. It was found that the overall haulage system generates about 27% of the fines of the coal produced monthly. The total monetary loss per shift from production and the wash plant is BWP 418,285. Coal dust concentration underground is kept within acceptable limits due to strict engineering control measures while it exceeds the required levels on the surface and is difficult to control as it is exposed to the atmosphere. As a result, the vegetation around the mining concession is affected by coal dust.   Fine generation; Dust production; Coal degeneration; Economic impact; environmental impact.

博茨瓦纳Morupule煤矿的罚款影响
Morupule Coal Mine (MCM)将细粒煤分类为小于3.35 mm的煤颗粒。罚款是MCM面临的问题之一,偶尔会导致一些客户的罚款。本文量化了从工作面到回采储存库中MCM产生的细粒及其对经济和环境的影响。通过检查错过的最后期限、由于尾端堵塞而停工以及使用公司报告的传送带故障,收集了有关洗涤厂生产损失的数据。煤尘浓度的数据是从该矿获得的。研究发现,整个运输系统产生的煤粉约占月产量的27%。生产厂和洗涤厂每班的总经济损失为418,285英镑。地下煤尘浓度由于严格的工程控制措施而保持在可接受的范围内,而地表煤尘浓度超过规定水平,并且暴露在大气中难以控制。因此,矿区周围的植被受到煤尘的影响。细一代;粉尘生产;煤炭变性;经济影响;环境的影响。
