| At present,the development of digital mines remains at a stage where only static geological structure,ore body shape and roadway engineering can be displayed.Although it plays a key role in mine production operations,this only reflects the information at a certain time.As a result,real-time information such as property changes or spatial changes that occur over time in an object's state,and events that cause various changes in the object,must be addressed.This requires the establishment of a spatiotemporal data model to manage the production of underground mines.First of all,through a large number of data reading,literature review,the existing spatio-temporal data model is summarized.Secondly,combined with the relevant knowledge of mining science,the mining underground mining production operations is analysed,including mine underground mining components,underground mining production operations processes.Then,according to the data characteristics and engineering features of underground mining,a multi-factor spatio-temporal data model of mining is proposed.It consists of five elements: object,time,event,attribute and association.Each element and its relationship are detailed.And,according to this spatiotemporal data model,database is designed.Finally,the underground mine mining system is developed by using Unity in VS.net platform.Through the development of system design and system function,the relevant functions such as roadway advancement and attribute inquiring are realized.Through the three-dimensional solid modeling,database design,system design and a series of steps to develop a mining underground mining system,mining business and mining entity data visualization and attribute data query are achieved.Meanwhile,it verifies the feasibility of mine multi-element model and realizes the management of mine spatio-temporal data,which makes the mine management more refined and promotes the digital development of mines in all respects and with high efficiency. |
