It's because the mining operations involve high costs. But you can significantly reduce these costs by using crushers. Since the mid 20 th century, mining accidents have significantly reduced. It's because the machinery used to perform underground mining operations enables the miners to obtain minerals in a safe way.

The HRX1000's innovative pick technology efficiently breaks down minerals in tension, reducing the need for multiple crushers and lowering operating costs. Its versatility makes it an invaluable asset in a wide range of mining applications.
Underground operations don't have the space for large crushers, so they typically use a steel grate called a grizzly to size material before it enters an ore pass.
Haulage alone plays a major role. Current haulage techniques are a significant cost driver, which account for between 15 and 30% of the overall capital investment (capex) in a mine and are an increasingly part of the operating costs (opex). The paper introduces a simulation tool of main haulage system in underground mining.

From 1937 to 1947, underground mining consisted mainly of robbing the pillars, back, and floor. Surface mining was started in 1944; and both surface and underground activity was carried on until 1947, when the underground operation was completed and the mine abandoned. Since that time the entire production has come from the quarry.
