Hlau Hniav Tricone Khoom
1, Mos formations (114-117)
Cov khoom no yog tsim los xyaum cov softest formations xws li mos shales, liab txaj, thiab av nplaum, nrog rau siab durability thiab siab tshaj plaws nkag mus.
2, Mos mus rau nruab nrab formations (121,124,126,134,136,137)
Cov khoom no yog tsim los laum formations xws li shales, nruab nrab mos limestone, Medium sandstone thiab lwm yam formations nrog intermittent nyuaj streaks.
3, Medium to hard formations (213,214,215,217)
Cov khoom no yog tsim los laum formations xws li nyuaj sandstone, dolomite, thiab tawg formations nrog nyuaj cherty streaks
