Usage Of High Power Lasers For Ultra-Hard Cutting

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 $167 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.

Dimension Stone Mining industry comprises the development of mine sites, mining and quarrying of dimension stones. Dimension stone products include blocks of rock such as marble, granite, limestone, sandstone and slate. Subsequent to cutting and polishing, these stones are used in construction of buildings and monuments, and also as exterior and interior decorative materials of buildings.

Crushed Stone Mining comprises crushed and broken limestone mining and quarrying, crushed and broken granite mining and quarrying and other crushed and broken sto

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.

The global stone mining and quarrying market was valued at around $142 billion in 2017. Asia Pacific was the largest region in the stone mining and quarrying market in 2017, accounting for around 54% of the market. China was the largest country in the market in 2017, accounting for more than 30% market share.
