中文2180字英文原文The Features and Prevention of the Gas Pouring from the BreakingCoal-bed of the Comprehensively Mechanized Mining FaceZhao JunhuAbstract:Through analyzing the features of the gas-pouring from the comprehensively mechanized mining face，thispaper advances some methods for making comprehensive treatment of the gas to ensure the safety in the production．Key words:gas-pouring；comprehensively mechanized coal mining；coal mine safety.Caving in thick coal seam mining widely used in the mining method .After several years practice and the exploration, applied this mining coal method to bring the remarkable economic efficiency.Simultaneously mines the technology also gradually to consummate, puts the coal thickness to reach 15 m.The peculiar circumstance has surpassed 20 m.Some syntheses set free a captured animal produce ability to achieve above 2,000,000 t/a. But along with the mining technology development and the application scope unceasing expansion, the synthesis picked puts goes against the coal also to bring a series of technical question under the specific condition.If mines in the easy ignition high methane coal bed the fire protection, dustproof, to guard against questions and so on gas.1 synthesis lets loose picks the gas to gush out the characteristicsynthesis to let loose picks is different with other lamination mining, its working surface and the coal bed relative position has had the change, is along ledger wall mining.The common around two conveyer transportation, one time picks big, productivity is big, upside the broken pulverized coal body is mobile to the support window, is braved the roof to fall the function to put the coal to be non-uniform, facilitates the gas to gush out also non-uniform. Added the fire protection note nitrogen influence, the cause synthesis lets loose picks the gas to gush out the question to appear the new characteristic, became affects the working surface per unit area yield the important attribute, simultaneously gave th
