Thousands Of Miners Contract Lung Disease After Long-Term Exposure To Dust

    Mining Design & Ventilation Expert

    This is a class action case of several thousand miners suffering from lung fibrosis as a result of their exposure to dust over the last twenty years. This litigation alleged that the mining companies that owned or operated 100+ different mines were aware of the dangers posed to miners by dust and chose not to take action to improve these conditions. It was alleged that the defendants failed to execute the steps mandated in regulations and legislation designed to protect miners from dust exposure. An expert in the proper design and ventilation of a mine was sought to explain how mine ventilation systems should be installed to reduce worker exposure to dust.

    Expert Witness Response E-098122

    I worked for a mine health and safety administration for 30+ years. At this is the agency, I worked on mine ventilation and dust control. I retired as chief of the dust division. Since retiring, I have worked as a consultant in the area of mine dust control. I have done studies in South America and Asia Pacific, as well as worked on product liability cases for U.S. equipment manufacturers. Most of these products cases were on behalf of defendants, however, I worked on a class action suit on behalf of the plaintiff. I can speak to technical issues of mine ventilation.
