PROJECT SUMMARY / ABSTRACTIn our prior Miner Safety and Health Training Programs - Western United States (U60) grants we developed theLearning Laboratories (LLs) program which is an industry-academic collaboration involving three universitiesand more than 20 mining organizations and operators representing over 20000 mine workers in the WesternUS. The LLs program provides needs-specific training resources and mentorship for miners trainerssupervisors and health and safety (H&S) professionals across all sectors of the industry. Operators participatingin the LLs program have shown measurable improvements in H&S outcomes including reductions in bothaverage injuries and days lost up to 23.6% and 72.5% respectively. Building upon these successes we willexpand our LLs program through three specific aims: 1) Provide new pathways for training and research throughcollaborative learning laboratories. Our LLs program offers a powerful mechanism for collaboration betweenresearchers safety professionals and industry trainers. The program will be expanded to meet all core elementsof NIOSHs Research to Practice (R2P) initiative. Specifically we will increase partnerships with trainers servingcontractors small operators and other underserved groups and MSHA State Grants programs. We will workwith investigators in academia and at NIOSH to identify industry needs deploy new and existing trainingmaterials facilitate synergistic research agendas and evaluate outcomes. We will enhance technology transferby streamlining deployment of new computer and app-based materials to industry partners for use in trainingand continued development. We will improve communication among LL partners through meetings workshopsand an online forum. We will facilitate evaluation through mentorship and a cloud-based data collection andanalysis platform. 2) Improve health training. By adding new health modules to our training materials manyNIOSH National Occupational Research Agenda (NORA) cross-sector topic areas will be addressed includingchronic disease musculoskeletal health hearing loss prevention respiratory health and heat strain. We will alsoincorporate Total Worker Health topics such as mental health substance abuse and fatigue. 3) Develop extendand integrate a continuum of training resources. Successful training products developed by our program NIOSHand LL partners will be upgraded to incorporate new content capabilities and interoperability. We will developresources addressing all levels of trainer capability from easily integrated tabletop games to computer-basedsynthetic learning environments (SLEs). We will improve the accessibility of training and evaluation technologiesparticularly for trainers serving smaller operators and at worksites lacking sophisticated computer hardwareusing app-based mobile games and streaming services. Intermediate outcomes will include: 1) Improved H&Spractices; 2) Workers empowered through active learning; 3) Increased sharing of effective training programs;and 4) An increased number of competent miners trainers supervisors and H&S personnel. The end outcomesof the program will include H&S culture change and reductions in mining injuries illnesses and fatalities.
