SMO BLOCK B1General Issue :

• Proses land compensation untuk area radius blasting di Enau harus sudah selesai pada awal tahun 2015 untuk menghindari terjadinya issue masalah blasting dan menghindari turunnya productivity unit karena ketidaktersediaan material blasting. (aktual blasting maks 50 hole)

• Rekomendasi IPD C 2015 masih menunggu kajian dan release GnH.

• Lokasi dumping material rawa/lunak diarea sump C.

• Pemotongan Mineout atau floor seam H 1 meter sesuai rekomendasi GnH.

• Performa slurry pump tidak maksimal pada pit G1 sehingga mengharuskan adanya manual handling, impactnya ada kenaikan SR karena perhitungan material blending 1:1.5

• Start Pumping di Sed Pond WMP 29 ( Slurry pump ) dan kontinyu pembentukan WMP 33
