It is mined from natural rocks through mechanical excavation generally involving drilling and blasting techniques. The extracted boulders of stone get hauled from inside the mines with ...

In quarries and mines, the drilling and the blasting activities is an essentially fundamental way of excavating rock. The blasting process is an integral and important part of mining operations and is intrinsically destructive for a variety of different reasons, notably efficiency, cost effectiveness and the capacity to shatter away even the most solid rock.

For years, the limestone was extracted by drilling and blasting and then wet processed into clinker in the cement plant. In a move to increase productivity and reduce costs, IFCEM became the first cement plant in the Ukraine to initiate the transition from the wet process to a dry process, a measure that optimized the mining method for material supply.

Blasting is the most widely used method to excavate limestone for cement production as the rock is usually too hard to be ripped or dozed. After blast holes are drilled, they are charged

Cement manufacturing is a significant industrial activity that plays a vital role in the construction sector. However, the process of cement production is associated with various environmental ...

The primary cement manufacturing process involves the mining of raw materials, mainly limestone and clay, which are used in cement manufacturing. In most of the cases, the limestone and clay are excavated from open cast mines by drilling and blasting and other appropriate processes in mines.

Optimisation of drilling and blasting phase is essential as the fragmentation obtained affects the cost of the entire production processes (Rout and Parida, 2007). The primary purpose of this …

A cement production plant consists of three major processes such as quarry and raw material preparation, clinker production and cement grinding and distribution [2]. During raw material preparation first, limestone and other raw materials are extracted using drilling and blasting techniques. Afterward, the quarried material is

The primary raw materials used in cement production are limestone, clay, and shale. These materials are typically extracted from quarries using various methods, including blasting, drilling, and excavation. Types of Raw Materials Used. Limestone: The most critical raw material, providing the calcium carbonate needed for clinker production.
