What is blast hole drilling?
Blast hole drilling is one of the main surface drilling techniques used in mining. It involves packing a hole drilled on the surface of the rock with explosive material and detonating.
Blast hole drilling effectively induces cracks in the surrounding rocks, which facilitates subsequent drilling and mining steps.
What drilling equipment is used in surface mining?
The common drilling equipment includes rotary, top hammer, down-the-hole drilling rigs. From the perspective of drilling efficiency, the range of rocks and hole straightness, DTH drilling rigs are unparalleled.
What are the advantages of applying DTH drilling rigs in solar panel installation projects?
There is huge demand of installing solar panels in a large-scale photovoltaic project. In this case, it is necessary to drill holes in various rocks efficiently and rapidly. Among a wide range of surface drilling equipment, DTH drilling rigs perform well in terms of efficiency, adaptability to rocks and hole straightness.
