Summary:The present invention relates to a stony mountain mining method using a natural ground barrier, capable of forming a vertical hole by connecting a lower space part, which is formed by horizontally excavating a lower part of natural ground, to one spot of a top part of the natural ground, and then quarrying stone while excavating the inside gradually downward by using the outer edge of the natural ground, thereby preventing blast vibrations, noise and dust, which are produced during excavation, from being exposed to the outside and developing a stony mountain in an eco-friendly manner. The stony mountain mining method using a natural ground barrier includes the following steps of: (a) forming a lower space part by horizontally excavating natural ground from a lower part of the natural ground to a center part of the natural ground; (b) forming a vertical hole by connecting one spot of a normal part of the natural ground with the lower space part in a vertical direction; (c) quarrying stone by excavating the natural ground in a barrier gradually downward in a state in which the outer edge of the natural ground is held by the barrier, and transferring the quarried stone to the lower space part through the vertical hole; and (d) carrying the stone, which is transferred to the lower space part, to the outside. 본 발명은 원지반 하부를 수평 굴착하여 형성된 하부공간부를 원지반 정상부 일지점과 연결하여 수직구를 형성한 다음 원지반 외곽을 차폐벽으로 하여 내부를 단계적으로 하향 굴착하면서 석재를 채석함으로써, 채굴 시 발생하는 발파 진동, 소음 및 분진 등이 외부에 노출되는 것을 방지하고 석산을 환경친화적으로 개발할 수 있는 원지반 차폐벽을 이용한 석산 채굴 방법에 대한 것이다. 본 발명 원지반 차폐벽을 이용한 석산 채굴 방법은 (a) 석산 원지반의 하부에서 원지반 중심부 측으로 수평 굴착하여 하부공간부를 형성하는 단계; (b) 원지반 정상부 일지점과 상기 하부공간부를 수직 방향으로 연결하는 수직구를 형성하는 단계; (c) 원지반 외곽을 차폐벽으로 존치시킨 상태에서 차폐벽 내부 원지반을 단계적으로 하향 굴착하여 채석하고, 채석된 석재를 상기 수직구를 통해 하부공간부로 이송하는 단계; 및 (d) 상기 하부공간부로 이송된 석재를 외부로 반출하는 단계; 로 구성되는 것을 특징으로 한다.
