薄煤层沿空留巷矿压观测显现规律研究

摘要

In the process of gob-side entry retaining implementation, in order to observe the surrounding rock activity law of two crossheading of gob-side entry retaining in the working face and during the secondary mining influence period, observe the deformation of roadway surrounding rock of roadway and obturator etc, we set the corresponding station in the process of gob-side entry retaining to observe the surface displacement and deep displacement of surrounding rock, and the stress variation of surrounding rock etc, in order to verify the effect of the gob-side entry retaining.%　　在沿空留巷实施过程中，为了观测两顺槽在本工作面留巷期间和二次采动影响期间的围岩活动规律，考察巷道围岩变形和充填体的变形，在沿空留巷过程中设置相应的测站，对围岩表面位移、围岩深部位移及围岩应力变化进行观测，以验证沿空留巷效果。
