Deere & Ault Consultants Inc. (D&A) has extensive experience with tunnels and mining projects, including numerous acid mine drainage control projects. Tasks have included geotechnical investigation, mine reclamation, grading, run on-run off control, mine hydrology investigation, control and treatment of impounded water, mine adit rehabilitation, and mine bulkheads. D&A staff typically oversees projects from initiation through construction. This gives them insight into the full range of mine development and reclamation.
D&A’s mining engineering experience comes from working not only with mining companies, but also with parties affected by mining, entities interested in the reclaimed site, and the mining/water resource regulators. This multifaceted experience allows them to understand the needs and concerns of all parties.
