RFQ:

1. What does surface casing serve as?
The purpose of the surface casing is to prevent lost circulation, segregate water sands, and guard against blowouts. Additionally, it typically offers enough shoe strength to drill into transition zones with high pressure.

2. Explain what a burden mine is.
The material that lies above a region that lends itself to economically viable exploitation, such as the rock, soil, and ecology that lies above a coal seam or ore body, is referred to in the mining industry as overburden (sometimes called trash or spoil).
