Research at the Poso river Tentena – Sulewana segmen and Meko river, North Pamona district and West Pamona District, Poso regenc, Central Sulawesi Province. Rock there research area is river alluvial with the potential mining are sand and rock boulders, the mechanical laboratory of rock boulders of point load test result 207,005 – 744,797 Kg/Cm square, fullselment required for building material. Environmental condition of Poso river there are infrastructure for people housing, road of Poso – Tentena (Trans Sulawesi) and Poso Hydroelectric Power at the Sulewana village and the bridge, Meko river there are people housing and the bridge of Tentena Pendolo, and the forest and the many people garden. At the Poso river Tentena – Sulewana segmen sand can mine but the water level of river much be constant the water level of river much be constant until save the Poso Hydroelectric Power, at the Poso lake sand mining is problem with use the sump machin of sand until 20 meters depth, means the lateral pressure is not save to lake wall and to bellow the safety factor from 1,25 to 1,00 is critical condition, if there little tremble is sliding. At the Meko River there are bridge facility of road Tentena – Pendolo much be not disturb.

Lithology of Tanjung Formation from the oldest to the youngest layers consists of siltstone, mudstone, dan carbonaceous mudstone or sandstone layers with four coal seams. Strike of joint varied N28ºE to N48ºE, N188ºE to N245ºE and N284ºE to N354ºE, and dip of joint varied 52º to 88º (very steep). Weathering conditions of rocks at the surface are moderately weathered (WM) to slightly weathered (WS) stage, and some of this surficial soils are at highly weathered (WH) stage as top soisl. In the bor holes these kinds of weathering stages (WM and WS) are characterized by both law core recovery dan RQD. Sedimentary rock of layer the joint to formed rock blok is discontinuity plane (bedding plane dan joint). The classification system is according to Rock Mass Rating (RMR) after Bieniawski, 1973 to determine the Slope Mass Rating (SMR) resulting maximum angle of cut slope of the rock mass in a stable condition. Rock Mass Rating (RMR) of penetrated rocks of the Tanjung Formation in Bore Hole No. AW-1, AW-2, and AW-3 range from 35 to 70, 40 to 50, and 29 to 60 respectively. The class numbers of the rock mass are II and III in general, suggesting that yhe rock masses are stable (class II) to partially stable (class III), but in Bore Hole AW-1 and AW-2 at the depth ranging from 39.45 to 45.30 meters and 04.75 to 27.84 meters (3 rock masses) respectively class IV occur characterizing the instable rock masses.
