6 FAQs about [Latest Dust Collection Down-the-Hole Drilling Rig Operating Procedures]
What is the best method for dust control in surface drilling?
The best method for dust control in surface drilling is to use wet drilling techniques. Wet drilling injects water along with the air to flush the cuttings out of the hole as shown in Figure 3.2. Testing has shown that this technique can provide dust control efficiencies up to 96 percent
What type of dust collection system is used in underground mining?
Typical dust collection system used by small crawler or "buggy‖ drills. Underground drilling is generally accomplished using percussion drilling with small diameter holes (up to 3 inches). Depending upon the type of underground mining method used, these holes can be oriented in almost any direction.
How does a drill dust collection system work?
The bailing air plays a crucial role in dust generation for medium- to large-diameter drills. The dust collection system consists of an exhaust fan and filters. The air, laden with dust, is drawn from under the shroud to the filters, which are periodically cleaned by backflushing.
Why is dust control important in surface drilling?
Effective dust control in surface drilling is crucial for health and environmental reasons. Methods like wet or dry drilling with dust collection systems are commonly employed. These techniques adapt to the specific operational environment and drilling equipment, ranging from small crawler rigs to large track-mounted drill rigs.
How does dust affect surface drilling?
Dust will reduce the operator’s visibility and equipment lifespan. Dust also impacts workers’ productivity and causes environmental, health, and safety problems. This article will review the main surface drilling techniques and dust control measures for different soil and weather conditions.
What are the safe job procedures for drill operation?
recommended safe job procedures for drill operation. It is designed for use in the training of dril operators and helpers. Where the dril crew is also involved in explosives transport should be used in conjunction with this module. excavators, drillng and blasting of the overburden is necessary. Highwall drils are used
