摘要
为了适应水电建设的需要,研制出适于在水电工程硬岩中钻进深井的LM-400型、LM-300型反井钻机,和用于单轴抗压强度达到310 MPa的极硬岩的滚刀,为拓展反井钻井技术应用打下基础。
In order to meet the needs of the hydropower construction, LM-400 and LM-300 type raise-boring machines were developed and manufactured. Such machines can be applied and used in the drilling in deep hole in hard rocks. And the roller cutters often used in extremely hard rock also was developed and manufactured. It can break the rock with 310 MPa compressive strength. All these techniques made a good foundation for the application of raise-boring technique.
