This book was released on with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: 2. Density The density of soil and rock materials is essential in understanding their load-bearing capabilities. Bulk density is defined as the mass of the soil or rock per unit volume, which includes both the solid particles and the void spaces between them. Specific gravity, on the other hand, is a measure of density relative to the density of water and reflects the inherent material properties. The relationship between moisture content and density is particularly significant. As water content increases, the density of the material changes, impacting its engineering behavior. Saturated soils will exhibit different properties compared to dry soils, highlighting the importance of considering environmental conditions in classification. 3. Moisture Content Moisture content is the amount of water contained in the soil or rock, expressed as a percentage of the dry mass. It is a critical factor influencing the behavior of both soils and rocks. In soils, moisture affects weight, cohesion, and plasticity. The Atterberg limits, critical for classifying fine-grained soils, define the boundaries of moisture content for various states: liquid, plastic, and shrinkage. In rocks, moisture plays a vital role in weathering processes and can impact the rock’s strength and durability. Saturated conditions may lead to changes in pore pressure, potentially causing instability, especially in cases where excavation or grading is being performed.

Download or read book Mechanical Excavation in Mining and Civil Industries written by Nuh Bilgin and published by CRC Press. This book was released on 2013-12-05 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: The secret to streamlined project scheduling is a solid understanding of basic rock cutting mechanics. Comparing theoretical values with experimental and real-world results, Mechanical Excavation in Mining and Civil Industries explains rock cutting theories for chisel, conical, disc, and button cutters. The authors provide numerical examples on the effect of independent variables on dependent variables, as well as examples from real-life mining and civil engineering jobs. The book assists students and engineers in machinery selection and performance prediction, and discusses rock cutting mechanics and mechanical miners.
Download or read book International Coal Preparation Congress 2010 Conference Proceedings written by Rick Q. Honaker and published by SME. This book was released on 2010 with total page 993 pages. Available in PDF, EPUB and Kindle. Book excerpt: The challenges facing the coal preparation industry have never been more complex or daunting: China, India, and South Africa are experiencing unprecedented growth in the use of coal. India is expected to be the world's largest importer of coal through 2030. New environmental regulations in the United States and elsewhere are forcing operators to be even more innovative and resourceful. How will the burgeoning demand affect global pricing? How can coal preparation companies employ more effective cleaning processes and technologies to reduce the environmental footprint of their mining facilities and waste storage areas? You'll find answers to these and hundreds of other critical questions in International Coal Preparation Congress: 2010 Conference Proceedings. This 992-page book is a compilation of 118 state-of-the-art technical papers presented at the industry's most prestigious gathering. A CD containing the full text is included. Read what coal preparation experts from 20 countries have to share on a variety of current issues.
