BMC 300型反井钻机的研制及应用

Development and Application of BMC 300 Raise Boring Machine

针对国内现有的反井钻机施工能力大都在深度200 m以内,而施工深度200 m以上井筒的机型体积较大、质量较大,不适合在相对狭窄、低矮的巷道中应用的现状,研制出用于钻凿300 m以内井筒,便于巷道内施工的BMC 300型反井钻机。介绍了该反井钻机的适用条件、技术参数和应用特点。该反井钻机在工程实践中,应用效果良好。

Based on the construction capacity of the domestic available raise boring machine was within the depth of 200 m, the machine volume was large, the big quantity was not suitable applied in the narrow and low mine roadway for the depth above 200 m, a BMC 300 raise boring machine was developed to bore a mine shaft within a depth of 300 m and suitable for construction in the mine roadway. The paper introduced the suitability conditions, technical parameters and application features of the raise boring machine. The good benefits were obtained from the application of the raise boring machine in the project practices.
