Geometri peledakan yang diterapkan PT. Semen Padang menghasilkan fragmentasi berukuran 55,955 cm dengan waktu penggalian 17 detik. Pada penelitian ini digunakan Geometri Peledakan dengan teori ICI- Explosive dan RL. Ash. Dimana Fragmentasi yang dihasilkan dengan Teori ICI-Explosive yaitu 36,766 cm dengan waktu penggalian 8,55 detik. Sedangkan dengan Teori RL. Ash fragmentasi yang didapatkan berukuran 34,49 cm dengan waktu penggalian 7,31 detik. Dari kedua teori tersebut, teori RL. Ash lebih baik karena menghasilkan fragmentasi yang lebih bagus.</mods:abstract><mods:classification authority="lcc">T Technology (General)</mods:classification><mods:classification authority="lcc">TN Mining engineering.
