深井软岩让压支护技术研究与应用

Deep Well Soft Rock Pressure Support Technology

针对深井软岩巷道支护的难题,结合平煤股份六矿三水平北二进风井井底车场巷道变形破坏的形态和特点,分析其破坏的原因和机理,根据其破坏的形态和规律,提出让压支护技术,采取"先让后抗"的分次、分阶段的联合支护技术,分步加固,动态维护,可有效控制深井软岩巷道的变形量,为深井软岩巷道支护提供有益的借鉴经验。

Based on the supporting problem of deep well soft rock roadway, combined with form and characteristics of intake well pit bot- tom drift deformation and failure on the third level of Beier 6 mine in Pingmei Environmental Energy Development Co. , Ltd. , and analy- sis the reason and mechanism of the damage, according to its destruction form and law, it suggested that pressure support technology, take ＂resistance after assignation＂ graded and grading combined support technology, and then consolidate, dynamic maintenance, which can effectively control the deep soft rock tunnel deformation and the soft failure roadway under high for deep well offer beneficial refer- ence for the experience.
