Common Applications of Borehole Stress Monitoring Systems

(>Because the goaf has the characteristics of strong concealment, poor spatial distribution characteristics, and difficulty in predicting the collapse of the roof of the goaf, how to analyze the distribution range, spatial morphological characteristics and goaf of the underground goaf Quantitative evaluation of the caving conditions has always been a key technical problem that has troubled engineering and technical personnel to evaluate the potential hazards of goaf areas and reasonably determine treatment strategies for goaf areas. After years of technical research and development, Weihai Jinghe Digital Mining Technology Co., Ltd. Finally overcoming this problem, Jinghe Company launched multiple product series such as Mine Star drilling stress monitoring system, ground collapse and settlement system, microseismic monitoring system, and three-dimensional geological imaging system for empty areas based on the principle of dynamic balance of stress in goaf areas. . The borehole stress monitoring system mainly monitors in the form of points. Monitoring points are selected to be set up in places that are prone to instability, and the points are accumulated into a network. This system is usually combined with the ground collapse and settlement system, using matrix tensile displacement meters, static force A variety of equipment such as levels and distributed optical fibers can be used to obtain ground subsidence and settlement data with an accuracy of no less than . Scanning technology, thermal imaging technology, ground-penetrating radar technology, etc., comprehensively display the shape and caving conditions of underground goafs in a three-dimensional form, providing mining technicians with unprecedented intuition and convenience.
: (>In view of the problem of goaf area, Weihai Jinghe Mining Star Mine goaf stability fully automated network monitoring system monitors the stress, strain, stress, stress, Displacement signals, comprehensive monitoring and integrated analysis of multiple parameters, maximizing the complementarity of various monitoring indicators, thus greatly reducing the cost of the monitoring system, improving the accuracy of disaster monitoring, and realizing disaster control in goaf areas. Real-time monitoring and early warning.
: (>Weihai Jinghe Digital Mining Technology Co., Ltd. has been committed to the research of mine safety technology for many years. It is a leader in monitoring and early warning of tailings ponds, goafs, slopes, tunnels, etc., and has With a number of technology patents and software copyrights, it has provided services to many leading mining companies such as China Gold, Zhaoyuan Gold Mine, and China Nonferrous Metals Corporation, and has been highly recognized by companies in the industry.
