Page 10 - Sidedumping can only be accomplished effectively in relatively steep terrain). • When fills are constructed by dumping from a higher elevation, there should be a good mix of end dumping and sidedumping (spoil tends to be plate shaped and dumping from one location will align material in a single plane creating slip failure planes). The fill should be benched for increased stability...
Page 36 - During final slope formation, the seedbed is prepared by spreading a suitable top material over the face of each completed lift. The dozer's cleat depressions are left to serve as seed traps. In a one-step operation the hydroseeder applies seed, nutrients, mulch and water to the prepared seedbed. A certain degree of freedom is permitted the operator in choosing the...
Page 151 - It must be emphasized that, while a certain amount of leveled mountaintop land is a highly desirable reclamation goal, development potential throughout much of this area is inherently low. It makes little sense to create unlimited developable land in an area where it is not required at the expense of the innate beauty of the region. This is not to say that the area should not be mined or that the adverse environmental impacts of surface mining in these regions are insurmountable or irrevocable, for...
Page 17 - TEMPERATURE--The maps of January and July mean monthly maximum and minimum temperature illustrate the winter and summer thermal patterns. Despite several considerable differences, the maps share a common feature: there is about as much temperature contrast across the State from east to west as there is in twice the distance from north to south. This condition prevails throughout the year, though it varies in magnitude with the seasons and cannot be expected to hold every day. Here the general effect...
Page 16 - ... the main part of the State in two parts. The eastern third of the plateau is part of the Appalachian Mountain chain and contains the highest land in the State. Peak elevations in this area range from about 2,500 feet to 4,860 feet (above sea level) at Spruce Knob, the highest point in West Virginia. The central and western thirds of the plateau slope generally westward to the Ohio River which lies at about 550 to 650 feet above sea level. In the north and west, the Allegheny Plateau has been...
