Usage Of High Power Lasers For Ultra-Hard Cutting

Posted by ananth on December 13th, 2018

The global stone mining and quarrying market, one of the major segments in the mining industry, grew at a compound annual growth rate (CAGR) of nearly 3% during the historic period. The growth can be attributed to an increase in demand for precious stones such as marble, granite, and limestone.

The global stone mining and quarrying market size is expected reach 7 billion by 2021, growing at a CAGR of around 4%. Over the forecast period, the growth is expected to be higher than the historic period. This is mainly due to advancements in the mining industry such as power lasers and rising demand from the construction market.

Mining companies are starting to use the combination of high power lasers with conventional mechanical drilling machines to enhance performance and reduce costs. Mechanical cutters are efficient in cutting soft rocks with low compressive strength. Most advanced mechanical cutters are not completely efficient in cutting ultra-hard stones. This slows down the drilling and also reduces the lifetime of drilling bits, resulting in poor performance and high costs. Drilling bits are tools that help in removing material and making a hole through the surface.

Lasers can be used to decrease the strength of the rock and then conventional mechanical cutters are used to cut the softened rocks. These lasers carry out high speed, accurate and safe drilling operations. The use of optical fiber output lasers to carry out cutting operations in mines provides razor sharp precision. It also enables low drilling cost per foot and longer life of the drilling machines.
