About this Exam

Prepare with the Advanced Mine Survey Certificate Exam Practice Questions - Advanced Certificate in Mine Survey (South Africa) Exam practice quiz. This question bank includes 100 questions covering angle, south, wire, distance, and underground. Use it to review important concepts, identify knowledge gaps, and build confidence for the related exam, course, or assessment.

Sample Questions

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?
To minimize the propagation of distance measurement errors into the calculated bearing of the wire baseline
To prevent optical parallax errors in the telescope reticle during short-range focusing
To ensure that the plumb wires remain within the field of view without rotating the horizontal plate
To eliminate the requirement for measuring the distance between the two plumb wires
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?
Meridian convergence correction
Magnetic declination correction
Grid scale factor amplification
Diurnal polar motion drift
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?
Immersing the plumb bob in a bucket of high-viscosity oil or water with dampening vanes
Attaching high-powered neodymium magnets to the bottom of the shaft liner
Increasing the tension beyond the yield strength of the steel piano wire
Enclosing the entire wire inside a pressurized pneumatic conduit tube
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?
00° 03' 30" (210 seconds)
00° 05' 02.4" (302.4 seconds)
00° 02' 10" (130 seconds)
00° 08' 24" (504 seconds)
Question 5
Why are roof pegs (spads) preferred over floor pegs for permanent survey control stations in underground development haulages?
Floor pegs are frequently disturbed or buried by track ballast, heavy mining machinery, and water accumulation
Roof pegs provide direct line-of-sight to surface satellites through rock fracture zones
Laser plummets can only project downwards from roof control points
Roof rock is completely immune to any closure, convergence, or strata movement
