Excerpt from A Study of Mine Surveying Methods: And Their Applications to Mining Engineering These notes, problems and observations have been compiled in order to present in useful form for the student much that is today scattered among various texts on surveying and much from practical work that is not included in the average series of lectures on mine surveying. The surveying of lode and placer claims has been omitted, as the present methods of conducting such work are very different from practice in underground work, and recent legislation has caused considerable confusion in all mineral surveys. Mine surveying is really one part of mining engineering. The purpose of these notes is to show how mine surveying enters into all the other phases of mining engineering and what methods are best adapted to each kind of work. It is assumed that the student has a good knowledge of the instruments and methods of plane surveying. He should be skillful in handling and adjusting the various instruments. Instruction in the art of adjusting the transit as used in mining work should be given before underground work is attempted Definition. The following definition is included in the introduction to Johnson's "Theory and Practice of Surveying" "Surveying is the art of making such field observations and measurements as are necessary to determine positions, areas, volumes, or movements on the earth's surface. The field operations employed to accomplish any of these ends constitute a survey. Accompanying such survey there is usually the field record, the computation, and the final maps, plats, profiles, areas, or volumes. The art of making all these belongs, therefore, to the subject of surveying." Mine surveying is generally defined as the art of making such measurements as may be necessary (a) to determine the location and extent of bodies of coal, ore, etc., (b) to determine the relative positions of points in the mine with regard to each other or to points on the surface.

Rock Slope Engineering covers the investigation, design, excavation and remediation of man-made rock cuts and natural slopes, primarily for civil engineering applications. It presents design information on structural geology, shear strength of rock and ground water, including weathered rock. Slope design methods are discussed for planar, wedge, circular and toppling failures, including seismic design and numerical analysis. Information is also provided on blasting, slope stabilization, movement monitoring and civil engineering applications. This fifth edition has been extensively up-dated, with new chapters on weathered rock, including shear strength in relation to weathering grades, and seismic design of rock slopes for pseudo-static stability and Newmark displacement. It now includes the use of remote sensing techniques such as LiDAR to monitor slope movement and collect structural geology data. The chapter on numerical analysis has been revised with emphasis on civil applications. The book is written for practitioners working in the fields of transportation, energy and industrial development, and undergraduate and graduate level courses in geological engineering.
Vol. 3- includes v. 190- of the Transactions.
