Conclusion (1) The development and utilization of underground space is an inevitable trend in sustainable development strategies. Leveraging existing transportation systems, safe and efficient well construction can be achieved through mechanical rock-breaking and gravitydriven slag removal technology. This approach facilitates the creation of large-volume
