The existence of coal reserves with a low level of peeled ratings is currently less so that coal-open mine applications become increasingly limited. This situation encourages the development of the Longwall underground mine application to exploit coal reserves in Indonesia. The Longwall method has a shortfall in terms of environment where the mining operation can cause a decrease in land. This land reduction can lead to various impacts on the surface environment where the mine is located. Therefore, to prevent or minimize the impact of the surface of the surface in the surface of an integrated monitoring or monitoring program. System development begins by reviewing the basic concepts of the mechanism of land-faced decreases covering the factors that affect large and extensive land reduction, the duration and method of prediction. Land-in-fire decrease management system is designed to provide an overview of the system and monitoring procedures for land decreases and links and file paths of the system. This management system also explains related personal responsibilities and their role in the development of procedures. The purpose of the land-in-face decrease system is to ensure the planning and implementation of a systematic monitoring system to support safe and efficient underground coal mining operations. This management system will be reviewed for improving the parts that are still lacking based on experience or based on investigation activities, analysis, planning, and designing new mining areas that will be developed in the near future. This system consists of a series of procedures and processes designed to ensure that the landfall consists of soil face run well and minimize the negative impact on the surface environment. Broadly speaking this system includes predictions of land reduction and monitoring design, procedures, training, inspection, auditing, review.
Application of writing
Integrated monitoring or monitoring program is needed to prevent or minimize the impact of the surface of the land.
