摘　　要：根据屯兰矿地质条件,提出综采工作面采用沿空留巷、"Y"型通风技术方案。针对沿空留巷工作面要求,通过对充填墙体在首次采动及二次采动条件下的受力分析,结合采场顶板活动规律与矿山压力显现规律的研究结果,完成充填体参数的计算与优化。为充填材料室内配比试验确定了目标,为沿空留巷技术的成功推广奠定了坚实的理论基础,为高瓦斯矿井综采工作面瓦斯治理探索科学的解决办法,为今后高瓦斯矿井安全生产提供了新的思路。On the base of TunLan mine’s geology conditions,the author put forward gob roadway and Y model ventilation scheme for full mechanized mining working face.According to the need of gob roadway working face,the parameter’s calculation and optimizing of roadway fill wall have been completed by analyzing the first and second mining affect and combining the rule of roof moving and mine pressure.The paper’s results afforded theory basis for gob roadway technology’s application,scientific solving method for gas preventing and the new idea for safe production in high gas mines.
