22、向扇形探測(cè)掘進(jìn)頭巷道上下探測(cè)控制距離為60100米。三、工作方法與技術(shù)要求根據(jù)近年來(lái)我所礦井物探理論研究及工程實(shí)踐表明:探測(cè)含水異常體采用礦井瞬變電磁法是最佳選擇。故本方案亦采用本質(zhì)安全型瞬變電磁儀。瞬變電磁法(TEM:Transient Electromagnetic Method)是一種脈沖感應(yīng)類電法,屬于時(shí)間域電磁法。它通過不接地回線向勘探目標(biāo)發(fā)送一次磁場(chǎng),測(cè)量一次場(chǎng)激勵(lì)電源關(guān)斷后一段時(shí)間內(nèi)的二次磁場(chǎng)變化,通過二次磁場(chǎng)衰減變化的信號(hào)特征來(lái)解釋和反演掘進(jìn)面前方的介質(zhì)結(jié)構(gòu)的性狀。瞬變電磁法的激勵(lì)場(chǎng)源主要有兩種,一種是回線形式(或載流線圈)的磁源,另一種是接地電極形式的電流源。下面以均勻大地的
23、瞬變電磁響應(yīng)為例,來(lái)討論回線形式磁偶源激發(fā)的瞬變電磁場(chǎng),從而闡述瞬變電磁法測(cè)深的基本理論。在導(dǎo)電率為、導(dǎo)磁率為的均勻各向同性大地表面敷設(shè)面積為S的矩形發(fā)射回線在回線中供以階躍脈沖電流 (1)在電流斷開之前(時(shí)),發(fā)射電流在回線周圍的大地和空間中建立起一個(gè)穩(wěn)定的磁場(chǎng),如圖3所示。圖3 矩形框磁力線在t=0時(shí)刻,將電流突然斷開,由該電流產(chǎn)生的磁場(chǎng)也立即消失。一次磁場(chǎng)的這一劇烈變化通過空氣和地下導(dǎo)電介質(zhì)傳至回線周圍的大地中,并在大地中激發(fā)出感應(yīng)電流以維持發(fā)射電流斷開之前存在的磁場(chǎng)、使空間的磁場(chǎng)不會(huì)即刻消失。由于介質(zhì)的歐姆損耗,這一感應(yīng)電流將迅速衰減,由它產(chǎn)生的磁場(chǎng)也隨之迅速衰減,這種迅速衰減的磁場(chǎng)又
24、在其周圍的地下介質(zhì)中感應(yīng)出新的強(qiáng)度更弱的渦流。這一過程繼續(xù)下去,直至大地的歐姆損耗將磁場(chǎng)能量消耗完畢為止。這便是大地中的瞬變電磁過程,伴隨這一過程存在的電磁場(chǎng)便是大地的瞬變電磁場(chǎng)。選用了煤炭科研研究總院重慶研究院自行研制的本質(zhì)安全型YCS-40瞬變電磁儀,該套系統(tǒng)完全能夠滿足本項(xiàng)目的要求,其瞬變電磁儀主要技術(shù)指標(biāo)如下:工作頻率:225Hz、75Hz、25Hz、8.3Hz、2.5Hz、0.83Hz、0.25Hz;發(fā)射電流:1A20A,發(fā)射供電電壓12V48V;記錄(時(shí)窗)時(shí)間:0.008ms864ms;疊加次數(shù):322048;測(cè)道數(shù):40道;存儲(chǔ)容量:2048個(gè)測(cè)點(diǎn);傳輸接口:RS-232C串口、USB口;傳輸格式:自定;傳送速度:28.8K/s。測(cè)量裝置可根據(jù)具體情況作出相應(yīng)的調(diào)整,一般情況下采用重疊回線裝置,偶極裝置;發(fā)射線框和接受線框采用多匝小回線圈,必要的情況下接受線框根據(jù)工作需要也采用相應(yīng)的磁探頭。掘進(jìn)頭探測(cè)形式扇形探測(cè)方式,分水平和垂直兩個(gè)方向掃描
