Design of Gob Gas Drainage Based on Similar Simulation Experiment Analysis
Abstract：In order to offer references for design of gob gas drainage with high-level borehole,Simulation experiment is made to study the law of overlying strata fall for 3088 working face in Donghuantuo Mining.Since off-white fine sandstone with the character of softening when meeting water,the character makes longitudinal fracture of off-white fine sandstone in overlying strata present the law of periodical penetration-no penetration by studying.The law of periodicity has important influence on float upward of gas.In order to gain better gas drainage result,the suggestion which design high level borehole combined with low borehole in working face for gas drainage is given in the paper.
