【摘要】：煤炭作為我國(guó)的主要能源,在國(guó)民經(jīng)濟(jì)的發(fā)展中發(fā)揮著重要的作用,隨著國(guó)家對(duì)煤礦產(chǎn)業(yè)結(jié)構(gòu)的調(diào)整,既需要對(duì)老礦區(qū)進(jìn)行維護(hù)也要對(duì)在建礦區(qū)加強(qiáng)監(jiān)測(cè),不斷提高煤礦的產(chǎn)量和效率。因此如何合理的對(duì)井筒進(jìn)行實(shí)時(shí)有效的監(jiān)測(cè)就顯得尤為重要,同時(shí)也要研究其內(nèi)在的基本規(guī)律以便于提前預(yù)測(cè)。本文分析了立井井筒的受力和井壁的混凝土破壞準(zhǔn)則,從而進(jìn)一步研究井筒的變形并對(duì)其監(jiān)測(cè)。結(jié)合童亭煤礦的工程項(xiàng)目,在跨越整個(gè)井壁上對(duì)稱(chēng)布置2個(gè)水平共8個(gè)井壁混凝土變形監(jiān)測(cè)點(diǎn)(每個(gè)水平對(duì)稱(chēng)布置4個(gè)測(cè)點(diǎn)),用以監(jiān)測(cè)井壁在第四含水地層段的豎向位移變化特征,以便獲得“四含”段的井壁豎向壓縮量的變化數(shù)據(jù)；地面人工觀(guān)測(cè)童亭礦區(qū)工廣范圍內(nèi)的地面沉降量隨時(shí)間的變化趨勢(shì),結(jié)合井壁豎向壓縮監(jiān)測(cè)的結(jié)果,為從理論上闡明童亭礦區(qū)的井壁變形與地面沉降的發(fā)生機(jī)理提供基礎(chǔ)數(shù)據(jù)；觀(guān)測(cè)礦區(qū)各含水層(主要是四含)水位變化特征,獲得含水層水位變化與相應(yīng)井壁豎向應(yīng)力變化和地面沉降之間的相關(guān)聯(lián)數(shù)據(jù),為井筒安全的預(yù)測(cè)預(yù)報(bào)提供監(jiān)測(cè)數(shù)據(jù)。綜合上述的數(shù)據(jù)來(lái)研究童亭煤礦副井井筒的地面變形規(guī)律。
[Abstract]:As the main energy of our country, coal plays an important role in the development of national economy. With the adjustment of the industrial structure of coal mine, it is necessary to maintain the old mining area and to strengthen the monitoring of the mining area under construction. Increasing the output and efficiency of coal mines. Therefore, how to reasonably monitor the wellbore in real time and effectively is particularly important. At the same time, it is necessary to study the basic law of wellbore in order to predict ahead of time. In this paper, the stress on the shaft and the concrete failure criterion of the shaft wall are analyzed, and the deformation of the shaft is further studied and monitored. Combined with the project of Tongting Coal Mine, Two horizontal and eight horizontal concrete deformation monitoring points are arranged symmetrically across the entire shaft lining (each horizontal symmetrical arrangement of 4 measuring points) to monitor the vertical displacement characteristics of the shaft lining in the fourth water-bearing formation, In order to obtain the variation data of vertical compression of shaft wall in "four containing" section, and to observe the variation trend of land subsidence with time in Tongting mining area, combined with the result of vertical compression monitoring of shaft wall, In order to provide basic data for explaining theoretically the occurrence mechanism of shaft wall deformation and ground subsidence in Tongting mining area, and to observe the water level variation characteristics of each aquifer (mainly four contents) in the mining area, The correlation data between aquifer water level change and vertical stress change of shaft wall and land subsidence are obtained, which can provide monitoring data for wellbore safety prediction. Based on the above data, the surface deformation of auxiliary shaft in Tongting Coal Mine is studied.
