Prevent and control geological disasters in mines, and promote intelligent mining construction projects

(2) Measures for preventing and controlling debris flows

Debris flow is one of the common geological disasters in mines. In the prevention and control measures of debris flow, it is necessary to start from two aspects: the first need to eliminate or solidified debris flow material, and the second is to eliminate the conditions of debris flow. First of all, in the process of eliminating debris flow materials, it is necessary to clean up the rubble, soil and soil on the slope of the mountain in time to avoid a large number of loose rubble and soil accumulation. If it can not be cleaned up in time, it is necessary to cure the soil, such as the use of cement mortar to fix it. To eliminate the induced conditions of debris flow, it is necessary to ensure that the water source is effectively controlled. In the prone to debris flow of the mountain to build drainage ditches, drainage channels, so that water can be effectively discharged, prevent debris flow, but also do a good job of greening work, through planting plants and other ways, effectively prevent soil erosion.

(3) Measures to prevent and control surface collapse

In the process of preventing and controlling surface collapse, it is necessary to reasonably design backfill parameters and slope parameters according to the specific characteristics of the mine, and strengthen the monitoring of the goaf. In order to prevent the phenomenon of surface collapse, the need to strengthen the pillar, and do a good job of stabilizing the slope, in the mining process, if there is a cracking deformation phenomenon, it is necessary to stop work immediately, and then let a professional geological exploration team to explore, and for the cracking deformation phenomenon to develop reasonable measures, while doing a good job in the tunnel to prevent the collapse of the mine top.

Mine geological disaster monitoring and early warning system

The Mine Star slope stability online monitoring system adopts wireless intelligent sensing technology, Internet of Things technology, cloud computing technology, embedded technology, communication and multimedia information technology. With the self-developed hardware and software monitoring system as the core, we provide users with timely and accurate monitoring data through reliable and practical monitoring system solutions. The displacement, stress and groundwater of the slope are monitored in real time by the monitoring system to predict the possibility of slope instability and the risk of landslide. It provides the technical basis for the prevention and control of landslide and the possible sliding and creeping deformation, and predicts the development trend of slope displacement and deformation in the future.

The on-line monitoring and early warning system of Mine Star is an automatic monitoring and early warning system using multi-disciplinary means such as integrated sensor technology, electronic technology, information technology, communication technology, computer technology and network technology. It can complete the functions of automatic collection, storage, network distribution and early warning display of deep ground pressure monitoring information, realize information, real-time and network, and grasp the actual dynamics of underground deep ground pressure safety parameters in time and intuitively. The system provides three monitoring methods: deep stress monitoring, section convergence monitoring, microseismic monitoring.

By establishing the ground pressure monitoring network suitable for the actual situation of the mine, the mine Star goaf online monitoring and early warning system can carry out long-term and effective monitoring of the ground pressure, and realize the effective monitoring and early warning of the geological disasters caused by the goaf caving and ground subsidence (or surface collapse, surface deformation). Goaf online monitoring system, with remote data transmission, remote status browsing, remote system Settings and data management, user management, safety management and other functions; It can timely and accurately discover abnormal data in the monitoring data, warn the instability of the goaf, and prompt the relevant management units to make emergency preparations in advance.

The construction of "six systems" for underground safety avoidance is an important means to improve mine emergency rescue ability and disaster handling ability, and ensure the safety of mine personnel. According to the technical requirements of mining enterprise safety avoidance monitoring and monitoring, communication and communication, and personnel positioning system construction, this plan consists of three subsystems: mine personnel management, communication and monitoring. Comprehensively monitoring the underground working environment and personnel scheduling, effectively guaranteeing the prevention of underground accidents, and providing strong support for underground refuge, plays a major role in ensuring mine safety production, and provides good conditions for underground mine safety production.
