【摘要】：摘要：開磷集團馬路坪礦段為緩傾中厚的破碎礦體,品位高,質(zhì)量好,但隨著開采向著深部邁進,出現(xiàn)回采過程中涌水量大、回采穩(wěn)定性差、回采困難、生產(chǎn)環(huán)境差等問題,導(dǎo)致回采貧化損失率高、成本高。針對以上問題,應(yīng)用超前快速疏干方法對深部礦體進行超前疏干處理,其創(chuàng)新點在于采用地下超前導(dǎo)孔進行超前疏干,超前將巖層、礦體中的地下水抽出,解決礦體回采過程中的水問題,保證回采的高效安全。這其中礦區(qū)水文資料的研究與調(diào)查是實現(xiàn)礦體超前疏干的基礎(chǔ)及關(guān)鍵,是確定超前導(dǎo)孔位置的關(guān)鍵,是提高疏干工程有效性的保證。考慮地下巖體中復(fù)雜的水文特性的因素,應(yīng)對深部大水礦體的超前疏干方案進行探究,對進行現(xiàn)場工業(yè)試驗,本文就此展開深入研究,得出以下成果： (1)對區(qū)域水文地質(zhì)條件進行調(diào)查,分析研究礦區(qū)的充水條件與涌水特征。對礦區(qū)的充水水源進行分析,確定礦區(qū)的充水水源及其比例,并結(jié)合礦區(qū)的前期調(diào)查資料,分析了礦區(qū)主要充水通道及其對礦床充水的影響。建立涌水監(jiān)測點與巖石淋水分級系統(tǒng),分析得出出水點空間特征與礦區(qū)巷道淋水度分級。 (2)完成了多個超前疏干方案,并對各個方案的實施方式、疏干效果等進行了論證。根據(jù)現(xiàn)場條件與技術(shù)條件,對各個方案進行比較,進行方案的初選。 (3)給出超前疏干方案優(yōu)選的ANP(網(wǎng)絡(luò)分析法)模型,并采用GMS對最終方案的可用性與有效性進行模擬驗證。通過采用ANP優(yōu)選出富水鉆孔超前疏干方案,采用GMS對其與巷道疏干進行模擬對比,驗證了其的優(yōu)越性。 (4)給出詳細(xì)的現(xiàn)場工業(yè)試驗工藝,并進行實際的現(xiàn)場試驗；得出現(xiàn)場施工經(jīng)驗,為后續(xù)大規(guī)模的現(xiàn)場應(yīng)用提供基礎(chǔ)；超前疏干過的礦房,涌水量明顯減少,礦石回收量明顯增加,創(chuàng)造了良好的經(jīng)濟效益,現(xiàn)場試驗獲得成功。
[Abstract]:Absrtact: the section of Maoping Mine of Kai-Phosphorus Group is a broken ore body with moderate and thick dip, which has high grade and good quality. However, with the development of deep mining, problems such as large water gushing, poor stability, difficult recovery and poor production environment appear in the process of mining.It leads to high loss rate and high cost.In view of the above problems, the advanced and rapid dredging method is applied to the deep orebody, the innovation of which is to use the underground leading guide hole to clear the ground water in advance, and to draw out the groundwater in the rock stratum and orebody ahead of time.To solve the water problem in the mining process of orebody and ensure the high efficiency and safety of mining.The research and investigation of hydrological data is the foundation and key to realize the advance drainage of orebody, the key to determine the location of leading guide hole, and the guarantee to improve the effectiveness of dredging engineering.Considering the factors of complex hydrological characteristics in underground rock mass, it is necessary to probe into the leading draining scheme of deep Dashu orebody, and to carry out the field industrial test. In this paper, the following results are obtained:1) investigating the regional hydrogeological conditions, analyzing and studying the water filling conditions and the characteristics of water gushing in mining areas.This paper analyzes the water source of water filling in mining area, determines the water source and its proportion in mining area, and analyzes the main water filling channel and its influence on the water filling of ore deposit in combination with the investigation data in the early stage of mining area.The water gushing monitoring points and rock sprinkling classification system are established, and the spatial characteristics of water points and the classification of roadway flooding degree in mining area are obtained by analyzing the characteristics of water points.2) several leading draining schemes have been completed, and the methods and effects of these schemes have been demonstrated.According to the field conditions and technical conditions, the various schemes are compared, and the primary selection is carried out.(3) ANPs (Network Analysis method) model is presented for the optimal selection of leading draining schemes, and GMS is used to simulate the availability and effectiveness of the final schemes.By using ANP to select the advanced drainage scheme of water-rich borehole, and comparing it with roadway dredging by GMS, the superiority of this scheme is verified.(4) the detailed field industrial test process is given, and the actual field test is carried out; the site construction experience is obtained to provide the foundation for the subsequent large-scale field application; the water inflow is obviously reduced for the mine house which has been drained in advance.The recovery of ore has been increased obviously, and good economic benefit has been created, and the field test has been successful.
