WATERPROOF SHEET TO PREVENT SOIL INFILTRATION OF LEAKING LEACHATE BY HEAP LEACHING PROCESS AND HEAP LEACHING SYSTEM INCLUDING THE SAME
A waterproof sheet according to an embodiment of the present invention is installed on the soil piled up with light during the heap-leaching process to prevent the leaking leachate from penetrating into the soil. And by including slack lime and fly ash, which are solid powder included in a waterproof layer forming the waterproof sheet at a ratio of 3:7 to 7:3, the permeability coefficient is lowered to less than 1Х10^(-5)cm/sec, so it is possible to significantly lower the penetration of the leaking leachate into the soil.
본 발명의 일 실시예에 따른 차수시트는 힙 리칭과정에서 조광을 쌓아올린 토양에 설치되어 누출되는 침출수를 토양으로 침투하는 것을 방지하기 위한 것으로서, 차수시트를 구성하는 차수층에 포함되는 고체분말인 소석회 및 석탄재의 비율을 3:7 내지 7:3으로 포함함으로써 투수계수를 1Х10-5 cm/sec 미만으로 낮춰, 누출된 침출수가 토양으로 침투하는 것을 현저히 낮출 수 있다.
