Book Description
Excerpt from Subsidence Resulting From Mining The subject of the subsidence of the earth's crust as a result of underground excavation due to mining has attracted Widespread attention for some years past, but particularly during recent years. With the extension of mining and the increased value of the surface above the mines in many localities, the growth of towns in mining regions, and the extension of railroads over mining properties, the subject is one that will be of increasing interest as time goes on, not alone to those engaged in mining coal and ores, but to the railroads, municipalities, and other owners and users of the surface that may be affected by mining opera tions. That the subject is not one of mere local interest is shown by the widespread distribution of surface subsidence as described in the follow ing pages. This bulletin has been prepared not with a View of bringing forward any new theories in regard to the subject, but it is in the nature of a reconnoissance and a statement of present knowledge of the subject, based upon the literature available up to the present time. It and a com panion preliminary Cooperation bulletin on subsidence in Illinois by Dr. Young, which will be issued by the Illinois Geological Survey, are intended as studies upon which to base a detailed cooperative investiga tion of. Subsidence conditions in Illinois. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Surface Subsidence in Illinois Resulting From Coal Mining It is undoubtedly to the interest of the State to conserve the coal supply by securing as complete extraction as possible from the areas in which mining is now being carried on. Almost one - half of the coal is being left in the ground and made unavailable for future mining, and in some places a large part of this abandoned coal is left because the mine operators fear that by removing a larger per centage they may cause surface subsidence and be required to pay damages out of proportion to the real value of the surface. In many places the surface may be restored at little expense. But until the prevailing conditions are known accurately and the essential facts are understood and studied, the State cannot consider or propose meas ures to relieve the mining industry of this severe burden.

Excerpt from Modern Practice in Mining, Vol. 2: The Sinking of Shafts It seemed, therefore, that a distinct want might be fulfilled by the contribution to mining literature of a work on the sinking and lining of shafts, which, while describing the methods ordinarily adopted, should also offer some account of such modern systems as are used under what may be regarded as exceptionable circum stances.
