Understanding Intermediate Speed: Legal Insights and Definitions
Definition & Meaning
Intermediate speed refers to a specific range of operational speed for diesel engines used in underground coal mines. It is defined as the maximum torque speed occurring between 60 percent and 75 percent of the engine's rated speed. If the maximum torque speed is below 60 percent of the rated speed, then the intermediate speed is set at 60 percent of the rated speed. Conversely, if the maximum torque speed exceeds 75 percent of the rated speed, the intermediate speed is capped at 75 percent of the rated speed.
Legal Use & context
Intermediate speed is primarily relevant in the context of mining safety regulations and engine performance standards. It is particularly significant in the mining industry, where compliance with safety standards is critical to prevent accidents and ensure worker safety. Legal practitioners may encounter this term in cases related to mining operations, equipment safety evaluations, and regulatory compliance. Users can manage related documentation through legal templates available on platforms like US Legal Forms.
Real-world examples
Here are a couple of examples of abatement:
Example 1: A diesel engine rated for 1,000 RPM has a maximum torque speed of 700 RPM. In this case, the intermediate speed is 70 percent of the rated speed, which is acceptable for operation.
Example 2: A different engine rated for 1,200 RPM has a maximum torque speed of 500 RPM. Here, the intermediate speed would be set at 720 RPM, which is 60 percent of the rated speed. (hypothetical example)
