【摘要】：我國煤礦每年都會發(fā)生很多礦井水災事故,給國家和企業(yè)帶來巨大的經(jīng)濟財產(chǎn)損失。礦井水災作為煤礦安全的五大災害之一,指礦井水從突水點涌出,沿著巷道淹沒井下空間的過程。隨著數(shù)字礦山在煤礦企業(yè)中的大力推廣,礦山信息化水平得到了顯著提升,通過對災害進行預測預報,使礦山安全性能得以提高。礦井水淹模型,是地理信息系統(tǒng)在礦山水文的典型應用。是以礦井地圖為載體,獲取某特定條件下礦井突水淹沒情況,實現(xiàn)在礦井空間中的模擬。礦井水淹模型,為礦井水淹過程的預測模擬,提供了理論依據(jù),也為科學高效地指導礦井水災救援,提供了技術(shù)支持。將在礦井水災的預測模擬中,發(fā)揮重要的作用,不斷服務于煤礦企業(yè)的安全生產(chǎn)。本文基于VRMine開發(fā)平臺,在礦井制圖的基礎(chǔ)上,建立起巷道的空間網(wǎng)絡關(guān)系,以網(wǎng)絡關(guān)系為基礎(chǔ),根據(jù)水流特征,設(shè)計并開發(fā)出礦井水淹模型算法。實現(xiàn)由突水點、淹沒水位或水量等監(jiān)測數(shù)據(jù),獲得井下被淹沒的巷道信息,模擬礦井淹沒的變化過程。進而可實現(xiàn)淹沒統(tǒng)計分析,淹沒預測分析,避淹路徑分析等功能。該模型以水淹算法邏輯、淹沒體積計算為支撐。文章核心介紹了巷道網(wǎng)絡構(gòu)建算法、水淹模型算法、水淹避災路徑算法等內(nèi)容,希望從礦井水淹模擬與預測方面,為礦井安全提供服務。
[Abstract]:Many mine flood accidents occur every year in our country's coal mines, which bring huge economic and property losses to the country and enterprises. As one of the five major disasters of coal mine safety, mine flood refers to the mine water gushing out from the water inrush point. Along the course of submergence of underground space in roadway, with the popularization of digital mine in coal mine enterprise, the level of mine informatization has been greatly improved, and the disaster prediction has been carried out. Mine water flooding model is a typical application of GIS in mine hydrology. The model of mine flooding provides a theoretical basis for the prediction and simulation of the process of mine flooding, and also provides technical support for the scientific and efficient guidance of mine flood rescue, which will be used in the prediction and simulation of mine flooding. This paper, based on VRMine development platform and on the basis of mine drawing, establishes the spatial network relationship of roadway, which is based on the network relationship and the characteristics of water flow. The algorithm of mine flooding model is designed and developed. The monitoring data such as water inrush point, submerged water level or water quantity are realized, and the information of underground submerged roadway is obtained, and the changing process of mine submergence is simulated, and the statistical analysis of submergence can be realized. The model is based on the logic of waterflooding algorithm and the calculation of submergence volume. This paper introduces the construction algorithm of roadway network, the algorithm of waterflooding model, the algorithm of waterflooding avoidance path and so on. The author hopes to provide service for mine safety from simulation and prediction of mine flooding.
