5.2. Metode Pengeboran 5.2. Drilling Method
Pelaksanaan pengeboran pada Blok Belani Drilling activities at Belani Block is carried out
dilaksanakan dengan memakai sistim grid, dengan using a grid system, with 50-100 meter distance
jarak antara cross line 50-100 m dan jarak antar of cross line and 10-75 meter drill hole spacing,
lubang bor 10-75 m, mengikuti jurus dan follow the strike and dip of coal seam with
kemiringan (down dip) perlapisan batuan hingga maximum Depth around 70-90 meter. The
kedalaman maksimal 70-90 meter. Hal ini bertujuan Purpose of grid system and control maximum
untuk memaksimalkan stripping ratio (SR) dan Dept for determine of optimization stripping
kemenerusan batubara. Rapatnya radius antar titik ratio (SR) and continuity of coal. The drill hole
bor disebabkan adanya indikasi tingkat spacing is relatively close, because drilling area
kompleksitas geologi yang tinggi pada area have high complexity geological condition, such
pengeboran khususnya adanya struktur geologi as structure geology fault with throw more than
patahan dengan offset (throw) lebih besar dari 20 20 meter. Beside that there are changed dip of
meter, bidang perlapisan (dip) yang berubah terjah coal seam from 26° to be 88°, strike of coal seam
dari 26° menjadi 88° dan jurus perlapisan (strike) from N 256 E to be N 135 E and fold major
dari N 256 E menjadi N 135 E dan terdapat pola presence at exposed of mining area.
