Applied study on mechanized control technology of floor heave in mine roadway

In order to meet the safety and high efficient control requirements of the floor heave occurred in the mine roadway, based on the construction characteristics of the surrounding rock control in the mine roadway, the technical idea of the floor heave mechanized control in the mine roadway and the allocation principle of the mechanical construction system. In combination with the construction condition and the mechanized control technical requirements of the mine roadway, a roadway repair machine, floor anchorage drilling rig and special major mechanical equipment were researched and developed and the technical structure characteristics and function features of the major equipment were analyzed. The completed set of the mechanized control technology was applied to the site engineering practices in Shaanxi Binchang Mining Area and Shanxi Yangquan Mining Area. The application results showed that the completed set of the technology and equipment could effectively improve the driving efficiency and safety level of the floor heave control in the underground mine, could highly reduce the number of the engineering construction personnel, could obviously improve the effect of the benefit increased and the cost reduced and could provide the reliable guarantees to the reduced personnel with the benefit increased and the safety production of the mine roadway.
