What is the maximum distance at which cross ties should be placed in a multiple row circuit?

• A. 50 meters
• B. 30 meters
• C. 70 meters
• D. 100 meters

Answer: (B)

In mining operations, cross ties play a critical role in maintaining the structural integrity and stability of multiple row circuits, often related to electrical or support systems. The standard practice typically recommends placing cross ties to limit excessive movement and maintain safety standards. The maximum distance of 30 meters for cross ties in a multiple row circuit reflects a guideline that balances operational efficiency and safety. By enforcing a closer spacing of cross ties, it ensures that forces acting on the circuit, whether from vibrations, load changes, or environmental factors, are adequately mitigated. This closer spacing reduces the potential for sagging, misalignment, or accidental damage that could arise if the spacing were too great. Considering the technical requirements and the need to adhere to safety standards, a maximum distance of 30 meters is well within the recommended practices, emphasizing the importance of preventing fatigue and excessive strain on multiple row circuits. This measure is essential not just for efficiency but also for ensuring the safe operation of mine systems.
