The underground green filling is a practical and effective way for harmless, recycling and large-scale disposal and utilization of multi-source coal-based solid wastes. In recent years, some coal mines in coal electrochemical construction sites actively try to adopt multi-source coal-based solid waste to prepare filling slurry for underground filling, so that not only is the problem of piling up of coal-based solid waste on the ground surface solved, but also ground surface subsidence, coal pressing resource loss and the like are reduced, and the multi-benefit of environment, society, economy and the like is achieved.
The preparation of filling slurry from multi-source coal-based solid waste is important for underground filling and monitoring. There are many observation devices on the market at present, and there are no lack of monitoring systems and methods in the filling process. However, the existing disclosed filling monitoring system and method are all carried out aiming at a certain link, such as pipeline pressure monitoring, flow monitoring, ground subsidence monitoring, working face mining pressure monitoring and the like, all monitoring works are independent of each other, do not form a system, lack links, are low in intelligent integration degree, monitoring data cannot be shared and cooperatively utilized, a certain information barrier and an information island are caused, and the guiding effect of the monitoring data is greatly reduced. The filling monitoring of the multi-source coal-based solid waste is different from the conventional solid waste filling monitoring, the filling material prepared from the multi-source coal-based solid waste has the advantages of wide sources, multiple components and complex components, the pollution monitoring is a primary task, and the key for determining whether the coal-based solid waste can be safely and environmentally used for underground filling is also determined. At present, in the practice of multi-source coal-based solid waste filling, the content of relevant pollution monitoring is less. According to the invention, a set of scientific, intelligent, standardized and procedural monitoring system is constructed through the monitoring modules and the monitoring contents in the whole process of filling (before filling, during filling and after filling) of the multi-source coal-based solid waste, so that the environmental risk brought by blind use of the multi-source coal-based solid waste in underground filling is reduced, the green, harmless, large-scale and recycling filling utilization of the multi-source coal-based solid waste can be ensured, and the filling monitoring efficiency and the management level are improved.

The intelligent monitoring system after filling comprises underground mine pressure monitoring, filling body monitoring, ground surface monitoring and underground environment monitoring. The underground mine pressure monitoring means that a pressure gauge, a displacement gauge, an ultrasonic surrounding rock detector, a drilling peeping device and the like are adopted after filling is finished to monitor the sinking, separation, pressure coming, rock covering crack development and the like of a working face and a top plate of a roadway. The filler monitoring means that ultrasonic wave, pressure and displacement sensors, drilling sampling, peeping and the like are adopted to monitor the compactness, solidification state, compression and stress conditions of the filler. The earth surface monitoring is to comprehensively monitor deformation parameters such as earth surface settlement, deformation value, curvature and the like of the filling working surface area and damage conditions of artificial facilities such as roads, building (construction) and the like by means of leveling measurement, RTK measurement, inSAR, fiber bragg grating and the like. The underground environment monitoring is to comprehensively monitor the earth surface soil, vegetation and the like of a filling area by using telemetry, remote sensing and the like, continuously monitor the change of indexes such as element content, pH value, suspended matters and the like of underground mine water, air and surrounding rock and the migration and conversion of key substances for a long time by using sampling test and the like, draw a space migration map of filling slurry in the underground, and evaluate the influence of filling on the underground environment.
The monitoring system and the monitoring result before filling, during filling and after filling are collected, monitored, called, displayed and the like in a centralized control center of a filling station in a modularized linking and management mode, and abnormal data and conditions obtained through monitoring in the whole filling process are fed back, prompted, predicted, early-warned and the like in real time, and correction, adjustment, inspection and the like of the up-and-down sites of the well are remotely guided in an intelligent and accurate mode.
