What is the maximum distance between cross-ties when multiple row patterns are employed?

• A. 50 feet
• B. 75 feet
• C. 98 feet
• D. 100 feet

Answer: (C)

The correct choice indicates that when utilizing multiple row patterns in mining operations, the maximum distance between cross-ties should be 98 feet. This standard is established to ensure adequate support and stability of the mining structure, preventing any potential hazards that may arise from inadequate support. Cross-ties serve a critical role in distributing load and maintaining the integrity of the mine structure. In operations where multiple row patterns are used, it is crucial that the cross-ties are positioned within a specific distance to ensure they are effective in their role. Distances beyond this maximum limit could lead to insufficient support, resulting in structural issues or safety concerns. While other distances may appear reasonable, they do not align with the established safety protocols and engineering standards necessary to maintain effective support in mine operations. Ensuring that cross-ties are no further than 98 feet apart aligns with best practices for ensuring the safety and structural integrity of the mining environment.
