Abstract

Abstract One of the basic stages of mining operations is development work. During them there can occur the events that affect the process of development work as well as the safety of workers. This article conducts a process risk assessment using the Failure Modes and Effects Analysis (FMEA) method to identify events that disrupt the development work process, along with the causes of the occurrence of these events. The study covered the process of development work i.e. the execution of the M-2 roadway in seam 502/1 realized at a depth of about 550 m with an assumed length of about 500 m. As a result of the study, those risks for which countermeasures should be applied were identified, and measures were proposed to minimize the risks involved. As part of the research, an FMEA evaluation form was created to assess process risks in the execution of similar work. The highest process risk was identified for the drivage of the excavation with a road header, and is related to the possibility of frequent failure of hydraulic systems. Similar process risk results were obtained for the risk associated with improper execution of mining with explosives and the need to perform additional blasting work in the excavated roadway. The results can contribute to reducing the time of coal face stoppage during development work, and thus improve the process of them and reduce the costs incurred during this process.
FMEA方法在煤矿危险源辨识和风险评估中的应用
采矿作业的基本阶段之一是开发工作。在此期间,可能会发生影响开发工作过程以及工人安全的事件。本文使用失效模式和影响分析(FMEA)方法进行过程风险评估,以确定破坏开发工作过程的事件,以及这些事件发生的原因。该研究涵盖了开发工作的过程,即在深度约550米、假定长度约500米的502/1煤层中实施M-2巷道。研究的结果是,确定了应采取应对措施的风险,并提出了将风险降至最低的措施。作为研究的一部分,创建了FMEA评估表,以评估类似工作执行过程中的过程风险。采用集管掘进的过程风险最高,且与液压系统频繁故障的可能性有关。对于与使用炸药进行不当采矿以及需要在开挖的巷道中进行额外爆破作业相关的风险,也获得了类似的过程风险结果。研究结果有助于缩短采煤工作面在开拓工作中的停煤时间,从而改进停煤工艺,降低停煤成本。
