Abstract

The traditional way of coal production and management is still predominant in the Indian coal mining industry which has led to a widespread waste of resources both materials and humans. Operational loss of the mining machinery and equipment is one of the key factors for the low performance and productivity of mines. This research presents an application of the integrated approach of the Mine Production Index and Ishikawa Diagram in an Indian coal mine to study the bottleneck equipment in the mining operation among the fleet of the shovel, dumper, and dozer. Mine Production Index (MPI) identifies the bottleneck equipment in the mining operation, and Ishikawa Diagram presents the Root Cause Analysis of bottleneck equipment. The fuzzy Analytic Hierarchy Process (FAHP) is used to determine weights for MPI calculation using information gathered from a group of 11 experts through Structured interviews. The study found that the dozer fleet is the bottleneck equipment and the ineffectiveness of the dozer fleet can be grouped into 4 categories as enumerated on the Ishikawa diagram. The study proposes that the ineffectiveness of the dozer fleet can be improved with an increase in its performance rate. The study is based on the judgments of the experts for the case mine, which may limit the external validity. This paper is an original contribution to the analysis of mining equipment using the Mine Production Index and Ishikawa Diagram in an Indian coal mine.

用矿山生产指数和石川图分析瓶颈——以印度煤矿为例

传统的煤炭生产和管理方式在印度煤矿业中仍然占主导地位，这导致了材料和人力资源的广泛浪费。矿山机械设备的运行损耗是造成矿山性能和生产率低下的关键因素之一。本研究将矿山生产指数和石川图相结合的方法应用于印度一座煤矿，研究电铲、翻斗车和推土机车队在采矿作业中的瓶颈设备。矿山生产指数（MPI）确定了采矿作业中的瓶颈设备，石川图给出了瓶颈设备的根本原因分析。模糊层次分析法（FAHP）用于使用通过结构化访谈从11名专家组收集的信息来确定MPI计算的权重。研究发现，推土机车队是瓶颈设备，如石川图所示，推土机车队的无效性可分为4类。研究表明，推土机的效率可以随着性能的提高而提高。该研究基于专家对案例的判断，这可能会限制外部有效性。本文是对利用印度煤矿的矿山生产指数和石川图分析采矿设备的独创性贡献。

期刊介绍： Scientific Mining Journal, which is published i n open access electronic environment and i n printed, is a periodical scientific journal of Union of Chambers of Turkish Engineers and Architects Chamber of Mining Engineers. The name of the journal was "Mining" until June 2016 and it has been changed to "Scientific Mining Journal" since September 2016 because it can be confused with popular journals with similar names and the ISSN number has been updated from 0024-9416 to 2564-7024. Scientific Mining Journal, published four times a year (March-June-September-December), aims to disseminate original scientific studies which are conducted according to the scientific norms and publication ethics at national and international scale, to scientists, mining engineers, the public; and thus to share scientific knowledge with society. The journal is in both Turkish and English. The journal covers theoretical, experimental, and applied research articles, which reflects the findings and results of an original research i n the field of mining engineering; review articles, which assess, evaluates, and interprets the findings of a comprehensive review of sufficient number of scientific articles and summarize them at present information and technology level; technical notes, which may be defined as a short article that describes a novel methodology o r technique; a case studies, which are based on the theoretical o r real professional practice and involves systematic data collection and analysis.
