Part 48 vs. Part 46 Applicability and Jurisdiction

  • Part 46 covers sand, gravel, surface stone, surface clay, colloidal phosphate, surface limestone, and shell dredging mines, plus certain surface operations of underground mines; Part 48 covers coal mines and all other metal/nonmetal mines.

  • Part 48 applies to underground metal/nonmetal mines and to all coal mines (surface and underground); Part 46 applies to the listed surface nonmetal operations only.

  • A mine operator determines which part governs by the commodity mined and the mining method (surface vs. underground), not by company size or state location.

  • Part 46 training is delivered under a training plan maintained by the operator; Part 48 training is delivered under a plan approved by the MSHA District Manager.

  • Part 48 new miner training requires a minimum of 40 hours for underground miners and 24 hours for surface miners before independent work.

  • Part 46 new miner training requires a minimum of 24 hours of training before a miner works independently at a mine.

  • Part 48 annual refresher training requires 8 hours per year; Part 46 annual refresher requires 8 hours per year.

  • Part 48 experienced miner training applies to miners with prior mining experience; Part 46 has a separate experienced miner category with a shorter training requirement.

  • Jurisdiction over a specific mine follows MSHA's determination of the commodity and operation; contractors working at a Part 48 mine follow Part 48, and contractors at a Part 46 mine follow Part 46.

Training Plan Requirements and Approval

  • Part 48 requires a written training plan approved by the MSHA District Manager before training is conducted; Part 46 requires a written plan maintained by the operator and made available to MSHA on request.

  • A Part 48 training plan must identify the mine, the operator, the courses offered, the instructors, and the training methods and materials used.

  • A Part 46 training plan must include the mine name, the operator name, the courses of instruction, the names of competent persons who will teach, and the evaluation procedures.

  • Part 48 plan amendments that change instructors or course content require MSHA approval before use; Part 46 plan updates are made by the operator without prior MSHA approval.

  • Part 48 plans must describe how training records are kept and how miners are evaluated; records of training must be retained and made available to MSHA.

  • Part 46 training records must include the miner's name, the training dates, the course content, and the name of the competent person who conducted the training.

  • Both parts require the plan to address new miner, experienced miner, task, and annual refresher training as applicable to the operation.

  • A Part 48 plan must be submitted and approved before a new mine begins production or before new miners begin work; a Part 46 plan must be in place before training begins.

  • MSHA may require revision of a Part 48 plan when the plan does not meet regulatory requirements; the operator must amend and resubmit for approval.

Trainer Qualification and Approval

  • Part 48 instructors must be approved by MSHA; instructor approval is granted based on qualifications submitted to and reviewed by MSHA.

  • Part 46 training may be conducted by a competent person, defined as a person who has the knowledge, training, and experience to teach the subject matter.

  • A competent person under Part 46 does not require MSHA instructor approval; the operator determines and documents competence.

  • Under Part 48, MSHA-approved instructors are required for new miner, experienced miner, task, and annual refresher training.

  • An MSHA-approved instructor approval is tied to specific courses or subject areas; an instructor approved for one course is not automatically approved for all courses.

  • Part 46 competent persons must be identified in the training plan, and their qualifications should be documented in training records.

  • State or industry certification alone does not substitute for MSHA instructor approval under Part 48.

  • Under Part 48, the District Manager may revoke or suspend an instructor's approval for cause, such as falsifying training records.

  • Contractor trainers at a Part 48 mine must also hold MSHA instructor approval for the courses they teach.

Basic and Annual Refresher Training Obligations

  • Part 48 new miner training: 40 hours underground, 24 hours surface, covering the required subjects before independent work.

  • Part 46 new miner training: 24 hours of training, including the required subjects, before the miner works independently.

  • Part 48 annual refresher: 8 hours per year for all miners, covering changes at the mine and required health and safety subjects.

  • Part 46 annual refresher: 8 hours per year for all miners.

  • Part 48 experienced miner training applies to miners with prior mining experience and covers site-specific hazards, health and safety aspects, and the miner's rights.

  • Part 46 experienced miner training has a shorter minimum than new miner training and covers site-specific hazards and required subjects.

  • Task training is required before a miner performs a new task; it covers the safe operating procedures for that task and must be documented.

  • New miners must receive training on miners' rights, including the right to request an inspection and to accompany the inspector, as part of basic training.

  • Training records must be retained: Part 48 requires records of training to be kept and available to MSHA; Part 46 requires records to be kept and available on request.
