Abstract

Sustainable regional development aims to increase regional competitiveness, increase economic growth, reduce regional inequality, and improve people's lives. South Sumatra Province is one of the provinces in Indonesia with excellent coal mining potential and can encourage sustainable regional development. The development of a sector cannot be separated from the support of other sectors, so optimizing the allocation of routine and development budgets into the economic sector is essential. For this reason, it is necessary to calculate the output impact analysis and analysis of the impact of gross value added on government expenditure using the input-output model. The calculation through this input-output model shows how much influence the increase or decrease in output and gross value added has on government expenditure. The role of the coal mining sector with other sectors and the condition of its existence in the economy need to be studied using the input-output table to determine the part of the mining sector in the regional economy. It can be concluded that the coal mining sector is still one of the leading sectors in economic growth in South Sumatra Province.

Abstract

The research location is in the coal mine area South Sumatera region, Indonesia. This study aims to determine the geomechanics relationship of the rock which includes the physical properties of the rock: bulk density, and mechanical properties of the rock (shear strength), cohesion and internal shear angle to the safety factor of the coal mine slopes in the study area. Field research is carried out by observing and measuring directly in the field in the following ways: (a) Measuring slope azimuth, slope, dip direction and slope height and width using a measuring tape and geological compass. (b) Rock description based on physical characteristics (megascopic) and rock sampling for testing the physical and mechanical properties of the rock in the laboratory. (c) Observing the general condition of water from rock slopes (dry, moist, watery, wet or flowing) and slope vegetation. 2. Cohesion values and internal shear angles are secondary data obtained from PT. X which has been analyzed in the laboratory. 3. Slope modeling was carried out using Rocscience Slide software. This shows that the smaller the rock density value, the greater the rock cohesion value. The greater the cohesion value of the rock, the smaller the value of the shear angle on the rock. The smaller the value of the shear angle in the rock, the greater the value of the safety factor of the rock slope.
