Our Excavation Process. Our excavation process is simple, effective, and safe. First, our professional team will blast rock from the quarry before moving it to our processing facilities. After the rock is processed it becomes construction aggregate that we are able to send to various businesses and sites throughout Queensland.
EXTRACTING THE ROCK. The process starts by breaking off large chunks of rock from the quarry walls, usually through controlled blasting. This rock is then moved using loaders and trucks to a primary crusher. THE PRIMARY CRUSHER. The crusher reduces the overall size of the material to make it easier to process.

Boral Quarries produces a range of useful materials based upon stone and rock. Suitable rock is extracted to make construction aggregates such as crushed rock, sand or gravel. These abundant yet essential raw materials provide the literal foundation of our homes, schools, hospitals, roads and almost all aspects of the built environment we depend on.
· The proposed quarry is on freehold land and is for the extraction of 50,000 to 100,000 tonnes of hard rock per annum for a period of 20 years. The material will be extracted by drill and blast methods and hauled by truck to a processing area for crushing and stockpiling on site.

Working hard rock quarries is generally a more complied and intensive process than quarrying sand and gravel. Typically, costs will be higher since technological issues have a greater bearing on the methods of excavation and the types of plant that can be used. Often, one of the overriding concerns in the design process is the operating cost ...
· The higher the compressive strength of rock, the higher also is its quality, which plays an important role particularly in road construction. A material's compressive strength is delineated into hard, mediumhard or soft rock, which also determines the crushing techniques used for processing to obtain the desired particle sizes.
