According to the difficulties that low recovery rate of coal resources, stressed coal mining connection, gas control in down-corner angle, based on the shipping lane geological condition of surrounding rock,Taoyi Mine of Handan Mining Industry Group recommended accommodating the deformation characteristics of surrounding rock of roadway along the empty left lane roadway support scheme and adopted ZKD high-water quick-setting filling material to fill gob side, gob-side entry retaining. The technology was simple and easy to transport, etc., The observation for left roadway surface showed that the average amount of displacement between two sides was less than 20 mm, the top floor was relatively closer to about 300 mm. It got good results.
