The importance of drilling and exploding solid mass structures
For any rock breaking work the drilling work has to be completed with precision. There have been several instances where a good plan was proved to be ineffective as the drilling was not up to the mark. A bad drill can ultimately fail the entire rock breaking operation. These drills are done in a synchronized way. Later, in these pre-drilled holes blasting agents are loaded for effective rock breaking. The most commonly used drill systems are rotary, percussive and rotary-percussive systems. The main personnel in charge of the blasting will inform the driller about the pattern in which the rocks are to be drilled. The entire drilling operation should be closely monitored to avoid any mistakes. The easiest way for breaking concrete drill the concrete with advanced concrete drilling tools.
Rock breaking can never be done on a fixed set of rules. Rock structures will differ additionally there will be cracks, shifts, changes in the strata, presence of sand and mud etc. In each case the drilling pattern has to be adjusted accordingly. Again, the rock surface may already have some natural holes in them. All these information have to be given by the driller to the person in charge of the blasting. The drilling operation alone can take quite some time.

The site of rock breaking is also needed to be inspected closely. Since, rock attributes are different the selection of the drilling tools will also be different. It demands a lot of experience from the person in charge to advise the right selection of tools for drilling. Once the drilling work has finished the blasting operations are initiated. Generally, bench blasting is the preferred method used for quarrying or mining. In some cases, the secondary blasting also becomes necessary. Each of these procedures has a fixed set of rules. As already mentioned there will be several hindrances in between. For instance, drilling and blasting operations can get delayed in rough terrains. In these places the loose top can cause problems while drilling. In such cases, different tools are needed to be used. Understanding the complexities involved in rock drilling and blasting newer systems are evolving to make the operation smooth and trouble free.
