Research on Cooperated and Continuous Non-Pillar Mining Technology

This thesis, making research on 4224 Mining District of Zhangcun Mine and combining with the geological features of the good lithological conditions of the roof and floor of the mining district and low gas content，etc, put forward the maintain roadways pattern of gob-side entry retaining, adopt adding anchor cables and erecting monomer pillar and other methods as the means to strengthen support, and effectively prevent the gangue to flow into the roadway by hanging grid on the up-side, and make research on ground behavior regular of gob-side entry retaining. Raise the transporting method that the face support move along the Gob-side Entry to the Open-Off Cut of the next section，which shorten the face moving route and moving time, achieve quick successival of the adjacent face. Meanwhile, continuous mining makes the surface appear continuous sinking, avoid the adverse impact on the surface of the sinking marginal basin, and minimize damage to the environment. Achieve the maximum recovery of coal resources, and minimize damage to the environment.
