Shulou(Shulou.com)11/24 Report--

Since the beginning of this year, the overall situation of mine safety production across the country has been stable, but coal mine accidents have continued to rebound. On August 30, 2023, the State Administration of Mine Safety issued the Circular on carrying out the Construction and networking of Slope Monitoring system in Open-pit Mines, and held a special meeting to convey important instructions. we should deeply absorb the lessons of the "February 22" particularly serious collapse accident in the open-pit coal mine of Inner Mongolia Alashan Xinjing Coal Industry Co., Ltd., and make every effort to do a good job in production safety in mines and tailings reservoirs.

● National Plan

It took three years to basically establish a national open-pit mine safety risk monitoring and early warning system, to achieve the identification, monitoring and accurate research and judgment of major safety risks in key areas and key links of open-pit mines, and to complete the construction of slope monitoring system of key open-pit mines in 2023 and carry out networking work.

● China Mobile Mine Slope integral solution

In recent years, based on the advantages of traditional operators, China Mobile has gradually deepened its network cloud capabilities and services, built a core competence system around the requirements of high-precision positioning location in the vertical industry, and built a "5G + Beidou" OnePoint spatio-temporal information capability base. Relying on the national strategy and industry policy, going deep into the field of infrastructure monitoring and testing, a mine slope safety monitoring system is established through multi-source perception, wide area identification, whole process monitoring, highly reliable operation and maintenance, efficient emergency response and rapid response. it can meet the needs of pilot projects all over the country.

Relying on the 5G + Beidou high precision positioning network, which is the largest in the world, it can provide accurate position data for slope deformation monitoring. Relying on the static deformation monitoring platform of China Mobile, the millimeter accuracy of deformation data can be achieved, and high-quality positioning services such as deformation monitoring, communication, online solution and multi-dimensional integrated services can be provided. Customized slope monitoring platform function coverage: mine monitoring project management, three-dimensional display, safety early warning push, online monitoring data, safety early warning, inspection management, emergency command and system management, big data analysis, etc. Close to the needs of the scene to build a business platform, security early warning response speed can reach seconds, has supported the landing of a number of 10 million-level projects.

● cooperates with industry leaders to build ecology to protect mine safety upgrading.

China Mobile gives full play to the leading role of central enterprises, taking the lead in the Beidou time chain, working with high-quality partners in the industry to solve the problems of the mining industry and solve the problem of industrial "neck sticking". Give full play to the advantages of operators, through provincial cooperation, antennae radiate the whole country, through provinces with cities, cities with localities, promote the construction of pilot projects, and create benchmarking project application demonstration cases.

Closely follow the requirements of national and local policies, cooperate with partners to build localized capacity, go deep into the demand side, clarify the technical application requirements in various environments, and work with partners to build a sound foundation for mine slope safety monitoring services. export integrated monitoring safety services to pilot projects all over the country.

● project case: slope monitoring project of Yinshan Mine of a certain group in Jiangxi Province

The mining area is about 6.75 square kilometers. Open-pit mining is a production process with high safety risk, so there is an urgent need to build a set of automatic safety monitoring system. Combined with the on-site environment and geological conditions of the mining area, China Mobile adopts Beidou high-precision positioning technology to realize millimeter-level deformation monitoring of the slope surface of the mining area; relies on the static deformation monitoring platform to carry out online data processing; ensures the fast and reliable upload of on-site monitoring data through the 5G network; integrates GNSS monitoring data and on-site rainfall data to evaluate the slope safety status, and automatically issues safety early warning for abnormal conditions.

The project successfully creates a set of multi-source sensing system with 5G + Beidou + sensor for the mining area, which realizes the automatic monitoring and management of the safety condition of the slope in the mining area, effectively assists the safety management, and reduces the workload and frequency of manual inspection on the spot. The labor cost can be saved by 100000 yuan per year.
