1982年列宁格勒矿业学院提出了采用探索-2型采煤机和“涅瓦”机械化气垛支架开采薄及特薄急倾斜煤层的回采工艺。国家设计院曾进行了技术设计,1985年完成了机械化气垛支架试验样机的制图工作,实验样机由斯达汉诺夫煤炭联合公司制造。使用气垛支架的“涅瓦”综采设备专门用于煤厚0.3～1m,倾角35～90°,工作 In 1982 Leningrad Mining Institute proposed the exploration of -2 shearer and “Neva” mechanized stacker mining thin and extra-thin steep seam mining process. National Design Institute has conducted a technical design, completed in 1985, the mechanization of gas-stack stent test prototype mapping work, experimental prototype by the Starhan Hanov coal joint manufacturing company. The “Neva” fully mechanized mining equipment using the gas stack support bracket is specially designed for coal thickness 0.3 ~ 1m, inclination 35 ~ 90 °, work
