About Limestone. Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite or aragonite. It is a kind of stone widely found in nature. Limestone can be directly processed into stone using crushing equipment and fired into quicklime. Quicklime absorbs moisture or adds water to become hydrated …

the Changjiu Shenshan limestone mining area, a total of four sets of blasting tests were conducted in the 1# and 2# mining areas. Specifically, three sets of blasting tests were carried out in the 1# mining area, while one set of blasting test was conducted in the 2# mining area. The location of each test set is illustrated in Figure 2.
The blast design for controlled blasting using electronic detonators could generate blast induced ground vibration less than 3.1 mm/s and 2.3 mm/s at 50 m and 100 m respectively from the blast site. Linear superposition technique has been used to simulate vibration level in full scale production blast using the single hole signature blast hole ...
1 Introduction. Deep-hole bench blasting is currently the primary method for aggregate extraction in mines. However, during the process of aggregate extraction, issues such as uneven rock fragmentation and high fines content often arise due to the complex geological conditions and suboptimal blasting process parameters (Roy et al., …
