The effort to reduce and eliminate the dangers of mining activities by preventing losses that is by implementing the application of safety management. Safety management systems are applied throughout the world. The world gets permission for industrial safety and health to get occupational safety and health. This safety management system is not only applied in Indonesia but also applied in several other countries such as South Korea, Singapore, Malaysia and Australia. In this study an analysis of the differences in the safety management system in these countries with an outline with the aim to carry out an analysis of the safety management system in large rock countries. The comparison obtained from the management system required and applied by the government regarding the safety system in these countries. For Indonesia and Singapore, a safety management system must be implemented in industrial companies, whereas for countries such as South Korea the safety management system is voluntary in other words the safety management system is implemented voluntarily by the industry. Australia is more applying safety management system standards and references for industrial needs. Safety management systems in Australia, South Korea and Malaysia are being readjusted to suit industry needs.

Penelitian ini dilakukan di PT Keritang Buana Mining yang berada di wilayah Izin Usaha Pertambangan (IUP) Desa Keritang Kecamatan Kemuning Kabupaten Indragiri Hilir Provinsi Riau. Tujuan penelitian ini yakni untuk mengetahui penyebaran cadangan batubara dan merancang desain pit di daerah potensial untuk ditambang. Beberapa parameter dalam perancangan pit tambang adalah penentuan batas akhir tambang, bentuk design pit, design bench (jenjang) serta penentuan cadangan batubara. Perancangan pit dilakukan di blok baru yakni Blok I seluas 54 Ha dari luas keseluruhan Wilayah Izin Usaha Pertambangan (WIUP) yakni 974,04 Ha dengan penyebaran batubara dari barat laut ke tenggara. Berdasarkan hasil pemodelan sebaran batubara ditemukan 1 seam batubara yakni seam S2 dengan ketebalan 1-1,2 meter. Berdasarkan rekomendasi studi geoteknik yang dilakukan oleh PT Keritang Buana Mining dalam perancangan pit batubara parameter geometri jenjang yang direncanakan  yakni lebar jenjang 5 meter dan tinggi jenjang 10 meter dengan kemiringan high wall 60° dan low wall 45°. Di lokasi penelitian dilakukan perhitungan cadangan dengan membagi luas potensial area tambang menjadi blok-blok dengan ukuran 50 meter x 50 meter untuk setiap blok dengan metode blockstrip menggunakan perangkat lunak simulasi tambang. Berdasarkan hasil perhitungan cadangan pada seam S2 didapatkan cadangan batubara 232.765,5 MT dan volume overburden 3.042.710,2 bcm dengan stripping ratio 13. Hasil yang didapatkan dalam perancangan pit ini sangat dibutuhkan dalam implementasi di lapangan guna dilakukannya penambangan batubara yang optimal berdasarkan parameter teknis dan geoteknik. Dengan volume cadangan yang akan ditambang 232.765,7 MT dengan stripping ratio 13:1 bisa dilakukan penambangan dikarenakan kualitas batubara didaerah penelitian termasuk kualitas batubara tinggi.
