I study mining engineering, and now there are coal mines and cement plants to recruit us. I worked as an intern in a coal mine, and I don't like the underground environment very much. The environment of cement plant is not. Generally speaking, it is not good for those who study mining to go to limestone mines. First of all, your major has not developed by leaps and bounds or as a whole. Moreover, limestone mines are all open-pit, with less difficulty and simple geological environment. There is not much you can learn from them. Generally, people promoted by cement plants are all people related to technology, and mining is not their main business. I don't know if I'm right. Generally speaking, cement plants pay far less attention to mines than rotary kilns. If you study mining, go to a big mine, whether it is a metal mine or a coal mine, but don't go to a limestone mine, it will really ruin a miner.

Generally speaking, limestone mining belongs to open pit mining or simple surface stripping. Besides the basic knowledge of mining and geology, the knowledge of blasting theory is very important and necessary! After work, it is necessary to have the safety operation certificate of blasting engineering technicians, which belongs to the technical title certificate and is divided into advanced, intermediate and primary. At present, the annual salary of advanced certificate holders is 6,543,800+million.
