The Strip Mining Handbook
1 FOREWORD 2 by 3 U.S. Rep. Morris K. Udall, Chairman 4 House Interior and Insular Affairs Committee 5 January, 1990 6 Congressman Morris (“Mo”) Udall, tireless champion of the federal strip mining laws, passed away on December 12, 1998. This foreword, which first appeared in the 1980 edition of this book, is included in its entirety as a tribute to Mo and to his extraordinary efforts to protect the public and the environment from the ravages of strip mining. 7 8 9 In the 1960's and early 1970's coal strip mining quickly overwhelmed underground mining as the 10 dominant mining method. But the new mining methods brought ravaged hillsides and polluted streams 11 to the once-beautiful landscape. State governments proved ill-equipped to prevent the severe 12 environmental degradation that this new mining method left in its wake. From our rivers, forests and 13 Appalachian Mountains in the East, to our prime farmlands of the Midwest, to our prairies and deserts of the 14 great West, stories abound during this time of reckless coal operators devastating landscapes, polluting 15 the water, destroying family homes, churches and cemeteries, and threatening fragile ecosystems. Perhaps 16 the most tragic case of abuse came on February 26th, 1972, at Buffalo Creek in Logan County, West Virginia, 17 when a crudely constructed coal waste dam collapsed causing a flood that killed 125 people, left scores of 18 others homeless, and caused millions of dollars in property damage. Something had to be done. 19 I was proud to stand in the White House Rose Garden on August 3rd, 1977, to witness the President sign 20 into law a bill that I sponsored — the federal Surface Mining Control and Reclamation Act (SMCRA). -

Professionals Australia's Response on Behalf of Members in Relation to The
Professionals Australia’s response on behalf of members in relation to the proposed restructure PA met with engineers who work in the Engineering Division on two occasions at WNSW Parramatta offices with members dialling-in from regional NSW. PA encouraged members to put forward their professional views on the proposed restructure on whether it addressed existing problems. PA has received some very detailed responses from our members. It is clear there is a high level of concern that the restructure will have undesired impacts on both employees and the functions of Engineering. Many members have taken the opportunity to respond directly to the WNSW email address set up for feedback. This submission does not repeat those comments. This submission is concerned with the first order issue – Does the restructure enhance the undertaking of engineering functions by WaterNSW or not? The next level of concerns which appear to be the main focus of the input provided via the WNSW email are the detail of position descriptions and the arrangements for filling the structure. We understand such matters have also attracted a large number of comments and concerns from members. However, those issues arise only when the first order issue is satisfied. The focus of this submission is whether the restructure has accurately identified the deficiencies and whether the proposal will address those deficiencies. What can a restructure address? A restructure can address issues such as resourcing levels, specific function focus and functional alignment. It cannot address issues caused by dysfunctional organisational behaviour, lack of effective processes, etc. Does the restructure enhance engineering functions at WNSW? The view of WNSW engineers is that overall the restructure will not result in the enhanced performance of the engineering functions required by WNSW. -

In the beginning Sydney’s first water supply from the time of its settlement Sydney Water in 1788 was the little stream that wound its way from near A day tour of the water supply Hyde Park through the centre of the town into Sydney Cove. It became known as the Tank Stream. By 1811 it dams south of Sydney was hardly fit for drinking. Water was then drawn from wells or carted from a creek running into Rushcutter’s Bay. The Tank Stream was still the main water supply until 1826. In this whole-day tour by car you will see the major dams, canals and pipelines that provide water to Sydney. Some of these works still in use were built around 1880. The round trip tour from Sydney is around 350 km., all on good roads and motorway. The tour is through attractive countryside south Engines at Botany Pumping Station (demolished) of Sydney, and there are good picnic areas and playgrounds at the dam sites. source of supply. In 1854 work started on the Botany Swamps Scheme, which began to deliver water in 1858. The Scheme included a series of dams feeding a pumping station near the present Sydney Airport. A few fragments of the pumping station building remain and can be seen Tank stream in 1840, from a water-colour by beside General Holmes Drive. Water was pumped to two J.

Effects of Longwall Mining Subsidence on Ground Water
EFFECTS OF LONGW ALL MINING SUBSIDENCE ON GROUND WATER LEVELS WITHIN A WATERSHED HYDRAULICALLY ISOLATED FROM MINE DRAINAGE' Bogdan Staszewski2 Abstract: Surface and ground water resources are effectively preserved from depletion by underground mine drainage if impervious deposits of sufficient thickness and extent that underlie the aquifer avoid fracturing and undergo only plastic deformation resulted from the strata flexure. This does not mean, however, that these waters are not subjected to the effects of mining disturbance. Differential vertical settlement of the mine overburden and the ground surface can significantly affect flow pattern and water retention within a watershed area. This is evident, for example, in the areas of multi seam coal mining where the longwall method is used. The effects of this type of mining on water level were tested in a selected watershed where shallow water bearing deposits were entirely isolated from underground mine pumpage. Results of more than 7 years of field investigations were compared with data collected from other coal mining areas of various hydrogeological conditions. The study revealed a variety of water table responses on the postmining subsidence. Basically, changes of water table height in a given site above the point located at the top of aquifer base depend mainly on alteration of that point position against the local drainage base in the hierarchic structure of flow system. The relationship between the magnitude of ground subsidence and water level decline varies within the area of the subsidence trough, within the watershed, and among various watersheds of different hydrogeologic conditions. Except for the situation of hydrostatic flow conditions, lowering of water table elevation in response to the settlement of aquifer base was observed.
