Determination of Gas Content of Coal

Abstract :-
This is B.Tech thesis on “Determination of Gas Content of Coal” for Mining engineering. The build-up of methane in underground coal mines is a safety problem in the India and around the world. Determining the quantity of methane enclosed within a coalbed can be avital step in assessing the potential severity of gas problems in a new mine or in unmined areas of an existing mine. The gas content of a seam can be tested during the exploration stage from core drilled samples. Continue reading Determination of Gas Content of Coal

Designing of Surface Blasts

Abstract :-
A major part of mineral production comes from surface mining and there has been a rapid growth in this sector with the deployment of high capacity equipment .Increased production can be achieved from large capacity surface mines using heavy earth moving machineries. These machineries involve high capital cost, and thus, the mining engineers should plan to achieve the best performance from these machineries. Performance of them, especially the excavating and transporting equipments are largely depending on the blast results, particularly, fragment size, distribution and muck profile. Thus, proper blast design with a computational approach is a vital factor that affects the cost of the entire mining activities. Continue reading Designing of Surface Blasts

Production and Characterisation of Aluminium-Fly ash composite using Stir Casting

Abstract :-
Metal matrix composites (MMCs) possess significantly improved properties including high specific strength; specific modulus, damping capacity and good wear resistance compared to unreinforced alloys. There has been an increasing interest in composites containing low density and low cost reinforcements. Among various discontinuous dispersoids used, fly ash is one of the most inexpensive and low density reinforcement available in large quantities as solid waste by-product during combustion of coal in thermal power plants. Hence, composites with fly ash as reinforcement are likely to over come the cost barrier for wide spread applications in automotive and small engine applications.
