Owner Objective

The confidential client is one of world’s leading global building materials and solutions company, with a local presence in 80 countries.

During an internal audit of the plant’s quarry, an auditor indicated that haul trucks appeared to be operating at excessive speeds. To address the auditor’s comments, plant management engaged CEC to analyze the quarry’s system of haul roads.

CEC Approach

CEC evaluated the existing haul roads at the plant. This evaluation was prepared using topographic data of the plant site collected using CEC’s small Unmanned Aerial System (sUAS) and guidelines published by the U.S. Department of Labor’s Mine Safety and Health Administration (MSHA).

The primary focus areas of the evaluation were to determine if the existing haul road configurations were in compliance with the MSHA guidelines, to note deficiencies, and to set appropriate speed limits. CEC used factors such as the geometric configuration (grade, turn radii, super elevation) of the haul roads, lines of sight, performance capability of the largest truck in use at the plant to prepare suggested speed limits for the haul roads.

The evaluation identified that the existing haul roads had a number of areas that did not comply with the guidelines published in the MSHA handbook. The client incorporated CEC’s recommendations, which allowed the mining company to better comply with MSHA guidelines by redirecting traffic, reconfiguring the roadway, and adding signage to possibly prevent accidents or the receipt of citations.
