摘要
根据东欢坨矿2085孤岛综采工作面的实际情况,确定了具体的观测方案,对巷道围岩变形进行了详细的观测和分析,掌握了巷道表面变形规律,并且从沿工作面走向和沿工作面倾向2个方面研究了巷道深部变形规律,为巷道围岩变形治理提供了可靠依据,有效保证了人员安全和正常生产。
According to the actual situation of 2085 island fully mechanized mining face in Donghuantuo mine, the specific observation program is established. Roadway surrounding-rock deformation is observed and analyzed in detail. Then roadway surface deformation law is obtained, and roadway deep deformation law is researched from strike and dip. Reliable basis is provided for governing roadway fully mechanized deformation, and personnel safety and normal production are effectively ensured.
