Environmental Action Programs for Northeastern Pennsylvania Refuse Bank Removal/subsidence Monitoring.
NTIS: PB 214 535 Available for Reference At Bureau Libraries :529 pages
This project, sponsored by the U.S. Bureau of Mines, Division of Environment, addresses two major subjects: refuse removal and subsidence monitoring. The refuse removal task consisted of developing a methodology for selecting the most economical combinations of coal mine breaker refuse and rock banks, disposal sites, and material moving systems (trucks, trains, belt conveyers, and pipelines). To prepare plans for moving refuse in the Lackawanna Valley of northeastern Pennsylvania, refuse banks were inventoried, underground disposal sites identified, and unit cost data prepared for the various material moving systems. The subsidence monitoring task consisted of defining the phenomenon of coal mine induced surface subsidence, establishing operational requirements, cataloging sensors, and techniques to detect and measure subsidence and testing of the most promising techniques (photoelastic patch, tiltmeter, strain gage, microseismic, and precise surveying). A preliminary system for a 700-acre area in Scranton utilizing 267 grid sensors, seven microseismic sensors and precise surveying techniques was designed with initial and annual operating costs determined.
