Mine Subsidence: Cause, Effect, Mitigation

Presented by: Dr. Gennaro G. Marino, Ph.D., P.E., D.GE

This presentation covers key aspects of mine subsidence engineering, a subject that is not well understood, and embraces a number of engineering disciplines. It focuses on the causes of mine subsidence and how mine stability relates to the resulting ground movements. Different mining and geologic conditions determine the mode of failure of the mine. The mode of mine failure in turn affects the resulting subsidence movement. Prediction of subsidence and damage potential are also key aspects of subsidence engineering. Case histories will be presented which illustrate different ground movement and damage scenarios. This presentation will be presented in a manner that will be understandable to anyone that would be interested in learning more about mine subsidence.

Speaker Bio: Dr. Gennaro G. Marino, Ph.D., P.E., D.GE

Dr. Gennaro G. Marino received his Ph.D. in Civil Engineering in 1985, from the University of Illinois. His thesis topic was related to mine subsidence and structural response to subsidence over room and pillar mines. Dr. Marino presently has a P.E. license in 27 states. Over the course of his career, Dr. Marino has authored over 100 articles and publications on subsidence engineering topics. In 2015, Dr. Marino received Distinguished Alumnus Award from the Civil and Environmental Engineering Alumni Association of the University of Illinois. In 2013, The Academy of Geo-Professionals (AGP) of ASCE recognized Dr. Marino as a Diplomate Geotechnical Engineer (D.GE) for his superior expertise and experience, strong ethics, commitment to life-long learning and continued professional development in the field of Geotechnical Engineering. In 2011, Dr. Marino was selected as the Central Illinois, ASCE Civil Engineer of the Year. Marino Engineering Associates, Inc. was chosen as 1st runner-up for the Central Illinois, ASCE Civil Engineering Project of the Year for 2010.

Working in the area of mine subsidence for over 40 years in various ore fields in the U.S., Dr. Marino has researched and consulted on all aspects of subsidence engineering with government agencies, engineering and architectural firms, surface owners, as well as pipeline, insurance and mining companies. His work includes planning, mining and abandonment stages of room and pillar to high extraction workings, as well as related cause and origin investigations.

Message from the Chair

Seasons greetings Oregon Chapter. We embark on our last month of 2020 and the beginning of a new year that hopes to bring an end to whatever 2020 was. In hindsight, 2020 had many challenges but I found that working from home has allowed more time with my family. I hope this time apart from the public has brought you all closer to your families as well.

We had a great talk from Tricia Sears and Bill Burns last month on the newly published land use guide for development in landslide susceptible areas. On December 17, Dr. Gennaro Marino will be giving us a presentation on mine subsidence.

The Oregon Chapter is looking for volunteers to help coordinate and operate the activities of the chapter. We are one of the lucky chapters to have had decades of dedicated individuals that donate a small amount of time to participate in building community with our local professional geologists.

Please do not forget to renew your AEG membership for 2021. Thank you for being an AEG member and supporting the opportunities for outreach and advocacy for the geology profession. Thank you so much for supporting our Chapter!

I hope the new year brings everyone great projects and much prosperity.

AEG Oregon Chapter Chair

Interested in presenting for the oregon chapter?

The Oregon Chapter is looking for great topics and presenters to provide content to share with the chapter. As we continue to navigate the virtual world, we will be holding the next foreseeable meetings through webinars. We currently have opportunities to present in November and December. Please consider presenting your exciting project to the Oregon Chapter. We look forward to hearing from all
of you and especially appreciative of those willing to present to the Chapter. If you are interested in presenting please feel free to contact any board member. Our contact information is at the end of the newsletter.
