Practice and Theoretical Thought on the Supporting for Soft Rock
The support of soft rock roadway is the worldwide problem in Coal resources exploitation, and this problem affect production safety and efficiency of coal mining serious. The surrounding rock of Ronghua coal mine is complex soft rock with expansibility, complex geological structure and deep high stress, large deformation of rocks, floor heave serious , supporting difficulties, frequent overhaul, waste a lot of manpower and material resources, and serious threats to the mine's safety production. After many years of practicing, a new idea of supporting the soft rock in different time periods, which is” avoiding first, then resistance”, was propounded. Based on the lithology of surrounding rock and geologic structure, the roadway’s length of service, application, and service condition were considered, several pointed support schemes of roadway in -650m level: Super-strong supporting, High-strong supporting, Flexibility combined supporting and Retractable U-shaped supporting were confirmed. A whole soft rock supporting technology system has been formed which effectively solved the difficult problems of soft rock supporting. These achievements can provide useful experience for similar engineering problems.
