我队钻进的地层均为峨嵋山玄武岩和阳新石灰岩，大部地层均为坚硬和中等硬度的白云质灰岩和辉绿岩，在辉绿岩中夹有两层风化程度不同、厚度不一的泥板岩和粘板岩，厚度在2～20公尺左右，硬度在4级左右，在风化厉害坍塌严重的情况下，为了防止坍 The formations in which my team got into are both the Emei Mountain basalts and the Yangxin limestone, most of which are hard and medium-hardness dolomitic limestone and diabase. Two layers of diabase are weathered with different degrees of weathering and different thicknesses Of mud slate and sticky slate, the thickness of 2 to 20 meters or so, the hardness of about 4, in severe weathering collapse serious case, in order to prevent collapse
