Gas Permeability Evolution Mechanism and Comprehensive Gas Drainage Technology for Thin Coal Seam Mining
A thin coal seam mined as a protective coal seam above a gas outburst coal seam plays a central role in decreasing the degree of stress placed on a protected seam, thus increasing gas permeability levels and desorption capacities to dramatically eliminate gas outburst risk for the protected seam. However, when multiple layers of coal seams are present, stress-relieved gas from adjacent coal sea...
متن کاملStudy on Compound Genetic and Back Propagation Algorithm for Prediction of Coal and Gas Outburst Risk
Coal and gas outburst is a very complex phenomenon of dynamic disaster in coal mine. There exists a complex non-linear mapping relationship which could not be described with functions between outburst risk and its influential factors. Due to the originality and superiority of artificial neural network (ANN) for modeling and imitating non-linear problems, an ANN model for prediction of outburst ...

چکیده حیطه ی نوشتار دانشگاهی اخیرا شاهد تغییرات عمده ای از غیرشخصی بودن (عینی بودن) به شخصی بودن بوده است. شخصی بودن متون دانشگاهی اهمیت استفاده از وجهیت معرفتی را برجسته می سازد چرا که? وجهیت معرفتی? بر اساس یکی از تعاریف ارائه شده از این مقوله? ارتباط تنگاتنگی با شخصی بودن داشته و به عنوان بیان نظر شخصی گوینده در مورد جز گزاره ای گفته در نظر گرفته میشود. بنابراین? با در نظر داشتن نقاط مشترک...
15 صفحه اولStudy of Gas Environment Impacts on Volumetric Coal Matrix Changes
The Outburst can be defined as a sudden release of coal and rock accompanied by large quantities of gas into the underground coal mine workings which represents a major hazard in underground coal mines. Gas drainage has been proven to be successful in reducing outburst hazards by decreasing the in-situ gas pressure. One of aspect of gas drainage from coal seams is coal matrix volume changes. Cu...
