Through proper re-mining, today's anthracite operators perform total reclamation by day- lighting these tunnels, removing the remaining coal, and re-establishing erosion and sedimentation controls, which in turn allow rain water to flow to stream naturally.
Mar 06, 2018· After mining, a coal company is required to restore the land it disturbed, e.g., by regrading or replanting. The federal government requires coal companies to get bonds to assure their payment for these activities. Federal law permits coal mine operators in some cases to guarantee these costs on the basis of their own finances, a practice known as self-bonding, rather than by securing a …

Two new coal-handling tunnels were needed: One to handle the raw coal and the other to handle the clean "product" coal. The raw coal tunnel needed to incorporate three chambers, including one for bobcat turnaround. The product coal tunnel needed to incorporate five different chutes to allow coal to be delivered from the stockpile above through a valve onto the conveyor below.
