【摘要】：為了保證武鋼集團(tuán)金山店鐵礦采礦生產(chǎn)的順利進(jìn)行，有效避免采礦過程中大面積垮冒所帶來的微震事件的發(fā)生，，武漢科技大學(xué)針對(duì)武鋼礦業(yè)公司金山店鐵礦地下開采區(qū)域進(jìn)行實(shí)時(shí)在線微震監(jiān)測(cè)。對(duì)金山店張福山鐵礦采動(dòng)微震事件進(jìn)行監(jiān)控，是預(yù)防事件發(fā)生的有效途徑之一。在金山店張福山鐵礦設(shè)計(jì)并布置了一套相適應(yīng)的微震監(jiān)測(cè)定位系統(tǒng)，采集微震信號(hào)，經(jīng)過EMD濾波、降噪等技術(shù)處理，得出非正常的微震波形，最后利用收斂速度快的牛頓迭代法，通過十六個(gè)傳感器的空間坐標(biāo)反算出震動(dòng)源的空間坐標(biāo)，確定震動(dòng)源位置，并在Hilbert變換的基礎(chǔ)上進(jìn)行初步的震源分類，為礦區(qū)采場(chǎng)提供依據(jù)，有助于預(yù)測(cè)災(zāi)害類型，并進(jìn)一步采取措施進(jìn)行有針對(duì)性的預(yù)防和控制，減少微震事件的發(fā)生。基于現(xiàn)場(chǎng)采集到的金山店鐵礦地質(zhì)資料和實(shí)驗(yàn)室分析的結(jié)果，決定將傳感器位置設(shè)置在張福山礦區(qū)-340m位置上，測(cè)取微震動(dòng)波形，進(jìn)行震源分析，預(yù)防安全事故的發(fā)生。綜合微震數(shù)據(jù)分析結(jié)合礦區(qū)實(shí)際情況進(jìn)行了微震事件震源分析研究以及對(duì)礦區(qū)影響程度給出科學(xué)評(píng)價(jià)，并對(duì)礦山下一步采礦生產(chǎn)作出合理的建議，在安全的前提條件下，最大限度地回收寶貴的礦石資源。這項(xiàng)研究對(duì)確保該礦采礦生產(chǎn)的安全、對(duì)指導(dǎo)下一步的生產(chǎn)工作、對(duì)礦山生產(chǎn)的決策等具有非常重要的意義。
[Abstract]:In order to ensure the smooth operation of the mining production of Jinshan iron mine in Wuhan Iron and Steel Group, and effectively avoid the occurrence of microseismic events caused by large area collapse during the mining process, the real time on-line microseismic monitoring was carried out in the underground mining area of the Jinshan store iron mine in the mineral company of Wuhan Iron and Steel Group (mineral company). Monitoring is one of the effective ways to prevent the occurrence of events. A set of adaptive microseismic monitoring and positioning system was designed and arranged in jinjindian Zhang Fushan iron mine. The microseismic signal was collected by EMD filtering and noise reduction. The abnormal microseismic waveform was obtained. Finally, the Newton iteration method with fast convergence speed was used to pass sixteen sensors. The space coordinates of the vibration source are calculated and the location of the source of the vibration source is calculated. The preliminary classification of the source of the seismic source is carried out on the basis of the Hilbert transformation, which can provide the basis for the mining area, and help to predict the type of the disaster, and further take measures to carry out the targeted prevention and control and reduce the occurrence of the microseismic events. Based on the field collection, The results of geological data and laboratory analysis of jinjindian iron mine decide to set the sensor position on the -340m position in the Zhang Fushan mining area, measure the waveform of the micro vibration, analyze the source and prevent the occurrence of safety accidents. The degree gives a scientific evaluation, and makes reasonable suggestions for the mining production in the next step. Under the condition of safety, the valuable ore resources can be recovered to the maximum. This study is of great significance to ensure the safety of the mining production in this mine, to guide the production work of the next step and to the decision of the mine production.
