Development of risk-based standardized WBS (work breakdown structure) for safety planning of coal mine project with surface mining methode

Abstract

The Mining Industry takes an important role in developing the country's economy, especially developing the country. Along with the increase in the coal mining sector, incident in the coal mining sector has decreased. Typical of coal mining activities is very strict safety regulations. Regulation in Mining Safety Management System is the role of the Indonesia government to be approved and provides clear rules in the OSH & Safety Operational system. Indonesian mining which must be applied by mining companies. Mining Safety Management System (MSMS) has begun to be implemented since 2014 in the mining sector, with Permen No. 38/2014. Then in 2018, it was replaced by Permen no. 26/2018, required 7 elements in the application of Mining Safety Management System. Standardized WBS can complement the planning element at MSMS, which is offered in updates related to work accidents. The purpose of this study was to develop a risk-based WBS standard particularly for coal mining project, by using a qualitative approach. The results of this study are WBS standard work standard for coal mining work with risk-based surface mining methods, there are 11 clusters of work, 34 work packages, 70 types of work and 325 work activities in coal mining. The development of risk-based WBS as a form of prevention, reducing and even nullifying the risk of work accidents in the implementation of coal mining projects.
