21、北5km到舊高山與109國道相接，鐵路有大同至舊高山運煤專線，生產煤炭可經大秦鐵路或北同蒲鐵路運往全國各地，交通十分便利，其交通位置示意圖見圖2。圖2 礦井地理位置圖二、工作目的與任務根據雙方簽訂的合同及煤礦水防治規定（國家安全生產監督管理總局令第28號）等相關法規、技術規范，探測目的與任務內容如下：在本礦各掘進頭的掘進過程中采用物探方法進行掘進頭超前探測，以查清迎頭前方80m范圍內的采空區、富水區分布情況及地質導水或富水構造，為甲方巷道迎頭掘進工作提供物探成果資料和安全措施。探測距離根據現場實際地質條件在80100米之間。掘進頭超前探測時，水平扇形探測掘進頭左右探測控制的距離60100米，縱

22、向扇形探測掘進頭巷道上下探測控制距離為60100米。三、工作方法與技術要求根據近年來我所礦井物探理論研究及工程實踐表明：探測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安全型瞬變電磁儀。瞬變電磁法（TEM：Transient Electromagnetic Method）是一種脈沖感應類電法，屬于時間域電磁法。它通過不接地回線向勘探目標發送一次磁場，測量一次場激勵電源關斷后一段時間內的二次磁場變化，通過二次磁場衰減變化的信號特征來解釋和反演掘進面前方的介質結構的性狀。瞬變電磁法的激勵場源主要有兩種，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、瞬變電磁響應為例，來討論回線形式磁偶源激發的瞬變電磁場，從而闡述瞬變電磁法測深的基本理論。在導電率為、導磁率為的均勻各向同性大地表面敷設面積為S的矩形發射回線在回線中供以階躍脈沖電流 （1）在電流斷開之前（時），發射電流在回線周圍的大地和空間中建立起一個穩定的磁場，如圖3所示。圖3 矩形框磁力線在t=0時刻，將電流突然斷開，由該電流產生的磁場也立即消失。一次磁場的這一劇烈變化通過空氣和地下導電介質傳至回線周圍的大地中，并在大地中激發出感應電流以維持發射電流斷開之前存在的磁場、使空間的磁場不會即刻消失。由于介質的歐姆損耗，這一感應電流將迅速衰減，由它產生的磁場也隨之迅速衰減，這種迅速衰減的磁場又

24、在其周圍的地下介質中感應出新的強度更弱的渦流。這一過程繼續下去，直至大地的歐姆損耗將磁場能量消耗完畢為止。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便是大地的瞬變電磁場。選用了煤炭科研研究總院重慶研究院自行研制的本質安全型YCS-40瞬變電磁儀，該套系統完全能夠滿足本項目的要求，其瞬變電磁儀主要技術指標如下：工作頻率：225Hz、75Hz、25Hz、8.3Hz、2.5Hz、0.83Hz、0.25Hz；發射電流：1A20A，發射供電電壓12V48V；記錄（時窗）時間：0.008ms864ms；疊加次數：322048；測道數：40道；存儲容量：2048個測點；傳輸接口：RS-232C串口、USB口；傳輸格式：自定；傳送速度：28.8K/s。測量裝置可根據具體情況作出相應的調整，一般情況下采用重疊回線裝置，偶極裝置；發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工作需要也采用相應的磁探頭。掘進頭探測形式扇形探測方式，分水平和垂直兩個方向掃描
