In gate road development, what types of values should be checked during inspection?

In gate road development, inspecting normal and non-normal values is crucial for ensuring safety and efficiency in mining operations. Normal values refer to the expected operational metrics and conditions that should be present during gate road development, including parameters related to airflow, rock stability, and ground conditions. These benchmarks are essential for assessing whether operations are functioning as intended.

Non-normal values, on the other hand, indicate variations or anomalies that could suggest potential problems, such as unexpected ground movements, ventilation issues, or water inflow, which could compromise safety. By routinely checking both normal and non-normal values during inspections, mine operators can identify and respond to emerging issues before they escalate into serious hazards. This proactive monitoring supports the overall integrity of mine structures and enhances the safety of personnel working in or around the gate roads.

The other choices, while relevant to mining operations, don't specifically pertain to the immediate technical concerns of gate road development inspections that focus on the operational environment and safety metrics needed to assess ongoing conditions effectively.
