How many types of rotary drilling rigs should be used for entering ten meters of weathered sandstone in the rock?
I now have a 31 SR280R rock drilling machine, hit ten meters of weathered sandstone, the estimated efficiency is not high, I suggest you can use 31 rotary drilling rig SR285RC8 or combination rotary drilling rig ZR360.
The current domestic rotary drilling rig manufacturers and models are more well-known manufacturers are mainly ZOOMLION, 31 heavy machine, Xugong, CSR, Futian, Shanghai Kim, Tianjin sunward, Bauer, Wujiang geotechnical, Yutong, mainstream rock into the rotary drilling rig has 31 main SR280R into the rock rotary drilling rig, Zoomlion ZR280 360, Xugong, Bauer BG25 into the rock can be, but the price is not high, 31 C8 series rotary recently to participate in the 2014 Shanghai BMW exhibition drill SR285RC8/SR385RC8, is said to have ability to exceed the traditional rock entering into the rock type rotary drilling rig.
