What is it about?
Slope on pits BMK-35 is dominated by sedimentary rocks, where the characteristics of rocks are influenced by geological structures so that rocks that are initially quite can become soft rocks when exposed when mining activities are carried out.

Why is it important?
We examine the rock compressive strength value that represents the pit slope of BMK -35. Moreover, this study also analyze the class rock mass with the SMR and the slope safety factor to prevent avalanche.
Perspectives
We hope this article is useful for mining engineers and geotechnical engineers to understand how to analyze slope Stability and prevent landslides early on, in order to minimize accidents.

Analysis stability of slope in BMK 35 to prevent avalanche
CV. Bara Mitra Kencana is one of the coal mining company in Sawalunto, Indonesia. The mining activities’ pattern of excavation yields natural and artificial slopes. Following observations in BMK-35 mining, it was regularly discovered that there were tiny failures and hanging rocks due to the abundance of rock discontinuity and excessively steep slopes of more than 80°. This study aims to analyze the strength of rocks by testing the Block Punch Index, analyzing the mass class of rocks with the SMR method, and knowing the safety factors using Software Slide Version 6.0. The test results obtained an average compressive strength for Sandstone of 0.3 MPa and 0.4 MPa for siltstone. While the UCS value from BPI is approximately 1.8 MPa for sandstone and 2.2 for siltstone. The acquired UCS measure is in use to determine the rock class. It is observed that the rock condition of the research object is poor category, the type of avalanche occur was the wedge failure. Pit slope safety factor BMK-35 was obtained by of 4.9.
