Based on under the close gob roof caving in the process of continuous mining of coal pillar, the first weighting and periodic weighting of mining face roadway, the upper coal seam floor strata movement change law was analysis. Goaf roadway intensive close arrangement along the way research was made. The close gob along the empty left lane pressure variation law of surrounding rock was summed up. The reasonable selection for the roadway support was formed, which finally realized a set of continuous mining technology under the close gob without coal pillar, freed the section and other protective coal pillar under the close gob mining area resources, essentially realized intensive centralization of efficient mining and efficient utilization of resources. The technology had application value.
