In the whole process of hydraulic drilling rigs and tunnel drilling rigs, due to external factors, such as loose rock formations and falling pebbles, these are very likely to cause common failures such as stuck drills. You must pay extra attention to this whole process. The following Anbitmechanical and Electrical Equipment Co., Ltd. will introduce some common problems to you.
①When you find that the rock formation is loose, chipped, pressure, water seepage or the water flow in the hole, the pressure suddenly increases or decreases, and the top drilling, you must stop drilling immediately, but do not pull out the drilling tool, and send someone immediately Monitor rain conditions and report to relevant departments quickly.
②In the whole process of drilling, when drilling through the empty area and discovering that harmful substances are sprayed out, stop drilling and increase natural ventilation, then use yellow mud grouting for reinforcement, and report to the mine dispatch center.
③When the rock layer is irrigated and drilled into the cast-in-situ slab or the bottom plate, the drilling must be stopped, the hole is damaged, and the waste hole is blocked, and no water is allowed.
① Before lifting the drill, open the lifting platform's braking system equipment, clutch equipment, lifting equipment and its special tools for tightening and unloading should be complete and powerful, and problems should be dealt with properly.
② Before lifting the drill, be sure to use a cold water punching machine to remove the rock dust.
③ During the whole process of lifting the drill, the driller must cooperate with other workers. The actual operation must be light and stable. Do not brake or release violently. Do not make it work with overload. Do not touch the galvanized steel wire rope with your hands. Other workers must be stay outside the scope of drilling equipment take-off and landing.
④ The core tube must be closed immediately after the tube opening is clearly specified. It is forbidden to explore or watch the core with your eyes.
⑤ The clearly proposed core must be cleaned and tidy.
⑥ The commonly used tools should be used for disassembly and assembly of drilling tools that are clearly proposed, and the use of drilling rigs for disassembly and assembly is prohibited.
The above is about the common problems in the whole process of drilling and clearing out the full hydraulic drilling rig for coal mining. I look forward to providing some assistance to you.
