Density Porosity The porosity was also calculated by the following formula according to : ma fl ma b D! !! ! (11) Where, Φ D = density derived porosity, ρ ma = matrix density (Sandstone = g/cm 3), ρ b = formation bulk density (the log reading), ρ fl = fluid density (Fresh water=1 g/cm 3).
The mining quarter has the top fatality expense of any within the kingdom. thankfully, advances revamped the previous 3 a long time in mining expertise, apparatus, techniques, approaches, and group schooling and coaching have considerably stronger protection and healthiness.
KEYWORDS: porosity, permeability, petrophysical properties, wireline logs. I. INTRODUCTION Petrophysics is the study of rock properties and their interactions with fluids (gases, liquid hydrocarbons and aqueous solutions). The amount of hydrocarbon present in a reservoir is a function of its porosity and its hydrocarbon saturation .

The ability to predict the performance and efficiency of drilling machines is very important in mining operations. The rock drillability is one of the most important parameters for mine planning, development and economics of mine operations. Also knowledge of drillability of rocks in engineering projects has key role to determine drilling costs.
The SME Mining Reference Handbook is a practical field reference for mining and minerals engineers who spend time away from the office. With its comprehensive store of charts, graphs, tables, equations, and rules of thumb, the handbook is the essential technical reference for mobile mining professionals.
The commercial mining of coal became widespread in the United States following the application of James Watt's 1769 invention of the steam engine to transportation and manufacturing. By 1880, coal had repla ced wood as the chief energy source for the world.
The drilling services are offered for geotechnical investigations, groundwater monitoring wells, water wells, mining, and seismic surveys. SOIL ANALYSIS Engineering Technology Services has the capabality to undertake a full suite of geotechnical analysis including;
Abstract. Rock physical and mechanical properties are very important parameters for geological engineering design and construction. For instance, in coal mining industry many geological disasters induced by mining were associated with misunderstanding of rock mechanical properties (Peng 1998a, Han and Peng 2002).

Based on the stratum subsidence, a program calculating porosity in overlying strata was developed based on VB. The results demonstrate that the porosity increase with face advances. The porosity becomes small with the decrease of strata depth, and the bigger separation is .
