Example Embodiment

[0021] Example 1

[0022] See attached figure 1 As shown, the present invention provides a WebGIS-based mine goaf monitoring and early warning system, which includes a surface monitoring collection subsystem, an underground monitoring collection subsystem, a WSN coordinator, a GPRS gateway, a remote monitoring management center, and an early warning information release subsystem. The surface monitoring collection subsystem and the underground monitoring collection subsystem respectively monitor and collect the surface information and underground information of the goaf in real time, and transmit the collected data information to the WSN coordinator through the wireless communication network, and the WSN coordinator is remotely monitored through the GPRS gateway The management center is connected to the communication, and the remote monitoring management center stores, analyzes, manages and processes information data and releases early warning information through the early warning...

[0032] Example 2

[0033] The invention provides a method for monitoring and early warning of mine goafs based on WebGIS, including:

[0034] ⑴Several surface monitoring nodes are arranged on the ground in the mined-out area of ​​the mine, and a number of underground monitoring nodes are arranged on the overlying rock layer and the empty area of ​​the mined-out area to form a wireless sensor star topology network, which connects the WSN coordinator, GPRS gateway and remote monitoring through the wireless network The upper computer of the management center; build a database, collect and store the geographical information, geological information, and disaster information of the historical record of the mine goaf through the database, sort out and analyze and process the information data, obtain the safety risk information data, and divide the types and levels of early warning; The early warning types include surface subsidence, ground subsidence, ground fissures and landslides, and m...

Abstract

The invention discloses a mine goaf monitoring and early warning system and method based on WebGIS, which are used for monitoring and early warning disasters such as mine goaf ground subsidence, ground fissures and ground collapse. The invention belongs to the technical field of geological disaster monitoring and early-warning. The problem that geological disasters in a mine goaf are difficult toaccurately and timely warn is solved; the system comprises an earth surface monitoring acquisition subsystem, an underground monitoring acquisition subsystem, a WSN coordinator, a GPRS gateway, a remote monitoring management center and an early warning information publishing subsystem. The WebGIS technology is used for monitoring the ground and underground of the mine goaf at the same time, the reliability of the early warning judgment result is improved, geological disaster prevention and control management departments and nearby people can know the geological disaster situation of the mine goaf in time, and losses are avoided.

Description

technical field [0001] The invention belongs to the technical field of geological disaster monitoring and early warning, and in particular relates to a system and method for disaster monitoring and early warning of goafs in mines based on WebGIS technology. Background technique [0002] Goaf subsidence is caused by the mining of ore bodies (layers) and the destruction of overlying rocks, mainly because the mechanical balance of the overlying rocks on the upper part of the ore bodies is broken after the ore bodies of various sizes buried underground are mined and excavated. In addition to its own gravity and stress, the rock mass produces fissures and dislocations, and groundwater enters through the fissures to seep into the goaf, which accelerates the destruction of the overlying rock, causes the rock strata and the surface to move, and finally forms the Mined out subsidence area. The subsidence area will not only lead to the depletion of groundwater, destruction of cultiva...
