1. Monitoring Background
The State Administration of Work Safety's "Opinions on Strengthening the Support System for Safety Supervision of Non-Coal Mines" (Document No. [2009] 204), and the Joint Notice by the State Administration of Work Safety and the State Flood Control and Drought Relief Headquarters on Ensuring Work Safety During the Flood Season for Mines, Tailings Ponds, etc., specifically emphasize the requirements for the construction of mine safety monitoring systems.
In addition, the "Notice on the Construction and Networking of Slope Monitoring Systems for Open-Pit Mines" (Document No. [2023] 119) issued by the National Mine Safety Administration outlines more detailed requirements for open-pit mine monitoring. The content is as follows:
To the mine safety supervision departments of all provinces, autonomous regions, municipalities directly under the central government, and the Xinjiang Production and Construction Corps, the provincial bureaus of the National Mine Safety Administration, and relevant central enterprises:
In order to thoroughly implement General Secretary Xi Jinping's important instructions and directives on work safety, to deeply learn from the particularly serious collapse accident at the open-pit coal mine of Xinjing Coal Industry Co., Ltd. in Alxa, Inner Mongolia ("2·22" incident), and to effectively prevent and curb major and serious accidents in open-pit mines, the National Mine Safety Administration has decided to carry out the construction and networking of slope monitoring systems for open-pit mines.
2. System Overview
The mine slope health automation monitoring system is based on the Internet of Things and big data technology. It conducts long-term automatic online monitoring of slope structures, stores monitoring data in the cloud platform, and grasps the health status of slopes in real time, and conducts health assessments and safety warnings in a timely manner. It provides a reference for slope management and maintenance and guarantees the healthy operation of slopes.

System function
Data acquisition and transmission function
The equipment of data acquisition and transmission system of our company mainly includes: data acquisition instrument, serial port server, A/D conversion equipment, transmission cable and wireless data transmission module. For each monitoring sub-item, the information collection and transmission node will be arranged according to the on-site environment of the structure, and the real-time data obtained by various parameter sensors will be uploaded to the central server host through the wireless data transmission module for data recording and analysis.
Reserved manual port for data collection and transmission
When manual monitoring is required, our company's data acquisition and transmission system still has a transmission port for manual portable acquisition instrument, which can collect data manually.
Data analysis function
The monitoring and analysis option is to organize the data collected and returned by all devices on site and display them in the system according to time. The system will self-diagnose the data to determine its validity, mainly by comparing the same group with historical data to see if it is a single mutation value. For effective data, the system will sort out and analyze the classification, and users can view and analyze the data they need.
Monitoring and early warning function
According to the different range of monitoring and control indicators, the early warning is divided into three levels for monitoring process management, and the monitoring data is compared with the three-level early warning value to determine the monitoring and early warning level of the site.
Information push function
Our online monitoring system works 24 hours a day without interruption. In case of abnormal conditions of structures, it will send early warning information to the user's mobile terminal. According to different alarm levels added by the user, the system will automatically send short messages according to the alarm level.
Report production function
The user can carry out to check out the data report export, after the user enters the system, you can download the data you need.
