Question 1
In shaft plumbing using the Weisbach triangle method, why is it critical that the instrument setup point forms an angle at the instrument (Weisbach angle) of less than 25 to 30 minutes of arc with the two plumb wires?
Correct Answer:
To minimize the propagation of distance measurement errors into the calculated bearing of the wire baseline
Question 2
When using a gyro-theodolite to determine an underground baseline bearing, which correction must be applied to convert the gyroscopic true north bearing to a South African LO grid bearing?
Correct Answer:
Meridian convergence correction
Question 3
Heavy plumb bobs suspended in vertical shafts experience continuous pendulum oscillations due to air currents. Which method is standard practice in South African deep-level mines to dampen wire oscillations?
Correct Answer:
Immersing the plumb bob in a bucket of high-viscosity oil or water with dampening vanes
Question 4
In a Weisbach triangle setup, instrument station A is placed nearly in line with plumb wires W1 and W2. The distance AW1 = 3.500 m, the distance W1W2 = 4.200 m, and the measured angle W1-A-W2 = 00° 04' 12" (252 seconds). What is the angle W1-W2-A at wire W2?
Correct Answer:
00° 03' 30" (210 seconds)
Question 5
Why are roof pegs (spads) preferred over floor pegs for permanent survey control stations in underground development haulages?
Correct Answer:
Floor pegs are frequently disturbed or buried by track ballast, heavy mining machinery, and water accumulation
