SH30-2A engineering survey drilling rig is mainly used in the geological survey of placer gold exploration, industrial buildings, civil buildings, roads and bridges. The drilling rig has two feeding modes, impact and rotary, and customers can equip it on demand.
[pdf] In this video we assemble a DIY micro drill rig (tiny DC motor + drill bit + frame) and a submersible water pump, then test drilling a small “well” and pumping water through tubing. I explain the mechanism, torque limits, and 3 upgrades for better performance.
[pdf] Drilling and blasting are the two most significant operations in open pit mines that play a crucial role in downstream stages. While previous research has focused on optimizing these operations as two separate p.
