Rock excavation is the process of removing rock material from the ground to create space for construction projects, such as buildings, roads, or tunnels. This process often involves the use of heavy machinery, such as excavators and bulldozers, to break up and transport the rock. Techniques for rock excavation can vary depending on the type of rock and the project's requirements. Common methods include drilling and blasting, where explosives are used to fracture the rock, and mechanical excavation, which uses specialized equipment to grind or cut through the rock. Safety measures are essential to protect workers and the surrounding environment during excavation.
