What is one of the main objectives of mine surveying?
A
To monitor wildlife around mines
B
To ensure proper direction and gradient of tunnels
C
To manufacture mining machinery
D
To drill boreholes for mineral samples
Analysis & Theory
One of the key objectives is to maintain the correct alignment and gradient of tunnels during mining operations.
How does mine surveying help in safety?
A
By designing safety boots
B
By controlling mine lighting
C
By monitoring ground movements and strata shifts
D
By measuring miners’ work hours
Analysis & Theory
Mine surveying helps detect ground movements or subsidence that could endanger mine safety.
Which objective relates to environmental control in mining?
A
Planning of ventilation systems
C
Determining shaft depth
D
Mining explosives planning
Analysis & Theory
Proper ventilation design is part of the mine surveyor’s objective to ensure air quality and safety.
Why is demarcation of mine boundaries important?
A
To prevent theft of equipment
B
To ensure mining stays within legal limits
C
To locate water sources
Analysis & Theory
Mine boundaries are demarcated to comply with legal regulations and avoid disputes or illegal mining.
Which survey operation helps calculate extracted ore volume?
Analysis & Theory
Volume surveys are conducted to compute the quantity of ore extracted and overburden removed.
Which of the following is NOT an objective of mine surveying?
A
To locate mineral deposits
B
To assist in mine layout planning
C
To design mining equipment
D
To link surface and underground measurements
Analysis & Theory
Designing mining equipment is not a surveying objective; it is the work of mining or mechanical engineers.
What role does mine surveying play in blasting operations?
A
Surveying doesn’t relate to blasting
B
Designing explosive chemicals
C
Helping with precise measurements and placements
Analysis & Theory
Surveying helps in planning and guiding the exact positions for blasting operations.
What is a primary goal of keeping updated mine records?
A
For environmental audits
B
To comply with legal and operational standards
C
To calculate fuel consumption
D
To track miner attendance
Analysis & Theory
Updated mine records help in maintaining legal compliance and improving operational control.
How does surveying contribute to economic mining?
B
By optimizing mine design and ore extraction
C
By increasing machinery speed
D
By enhancing fuel quality
Analysis & Theory
Proper planning and measurements lead to optimized extraction processes, reducing wastage and cost.
Which of the following is achieved by establishing control points in mine surveying?
A
Defining the work shift
B
Providing reference for accurate measurements
C
Controlling air quality
D
Monitoring mining speed
Analysis & Theory
Control points serve as references for horizontal and vertical measurements during the entire mining process.
