National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Blast Vibrations and Other Potential Causes of Damage in Homes Near a Large Surface Coal Mine in Indiana.

PB94125648

Publication Date	1993
Personal Author	Siskind, D. E.; Crum, S. V.; Plis, M. N.
Page Count	72
Abstract	The U.S. Bureau of Mines studied seven homes near Evansville, IN, that had various degrees of damage that the owners attributed to vibrations from surface coal mine blasting. Researchers monitored vibration and airblast impacts, crack behavior before and after blasts, and dynamic structural responses to blasting and other sources. Level-loop surveys were performed to quantify possible settlement and subsidence. These results were combined with State and coal company measurements to determine if recent vibration characteristics, airblast propagations, or structural responses were typical of results found in historical studies that produced criteria for safe blasting and regulatory limits.
