<br />
To add production capacities, UBPE Pongkor PT Antam, Tbk plan to make an incline shaft at Ciguha mine from level 500 to level 450. <br />
<br />
<br />
<br />
<br />
This research aim to estimate rock mass characteristic at incline shaft location and then recommend support system which matching with the rock mass characteristic. <br />
<br />
<br />
<br />
<br />
After analyzed by Q System (Barton, et al 1974), there is three section which must be gave attention during the incline shaft development because condition of rock mass which relative weaken, that is F section ( deepness: 21.65 - 25.65 m), G section ( deepness: 24.65 - 29.65 m) and H section ( deepness: 29.65-34.50 m). <br />
<br />
<br />
<br />
<br />
After this research better be conducted by monitoring to deformation at aperture hole wall which because of movement of rock mass and afterwards to analyse numerik by using data result of perception of aperture hole so that will be more be objective and the device aktual <br />
