The invention discloses a non-explosive mechanized intelligent mining method for deep hard rock ore bodies, comprising the following steps: S1, performing in-situ monitoring and sensing on the cuttability of ore rocks, and evaluating the cuttability of ore rocks and the applicability of mechanized mining , to identify the distribution position of difficult-to-mine rocks and quantify their degree of difficulty, and form a cloud map of the cuttability of the ore body to be mined; S2, to guide the method for improving the cuttability of hard rock ore bodies based on high stress-induced cracking and prefabricated defects implementation, so as to achieve precise improvement of the cuttability of difficult-to-mining ore bodies; S3, real-time intelligent control of rock-breaking methods and rock-breaking parameters of mining machinery, to achieve non-blasting mechanized mining; S4, verify and improve the cuttability of ore rocks Monitoring perception and evaluation methods and methods for improving the cuttability of hard rock ore bodies; S5, through comprehensive management and control through a digital information sharing decision-making platform based on Internet of Things technology, to realize non-blasting mechanized intelligent mining of deep hard rock ore bodies.
Description
technical field [0001] The invention belongs to the technical field of hard rock mining, and in particular relates to a non-blasting mechanized intelligent mining method for deep hard rock ore bodies. Background technique [0002] With the continuous development of science and technology and the increasing demand for mineral resources, mines at home and abroad are constantly developing towards deeper mining depths and gradually entering the category of deep mining. At present, the drilling and blasting method is still widely used in the mining of deep mines. However, due to the disadvantages of large blasting-induced damage, low energy utilization rate, and poor safety, researchers have proposed non-blasting mechanized mining with the advantages of small operation disturbance. And carried out relevant field application tests in deep mines. [0003] Deep mines are usually hard rock mines with good integrity and high abrasiveness. They are affected by high confining pressure....
