Health Hazards of Mining and Quarrying ... Silica exposure also occurs at stone quarries that must cut the stone to specified dimensions. The most common contemporary method of cutting stone is with the use of a channel burner fuelled by diesel fuel and compressed air. This results in some silica particulate.

This is not unusual, as it is probably the best method, and is still widely used today. In order to accurately split hard stone such as granite, a series of small holes are chiselled out, then filled with wood fibres which expand when soaked in water, thereby splitting the stone.

Old Stone Age and believed to be about 40,000 years old. Early miners employed crude methods of ground control,ventilation,haulage,hoisting, lighting,and rock breakage. Nonetheless,mines attained depths of 800 ft (250 m) by early Egyptian times. Metallic minerals also attracted the attention of prehistoric humans. In
