Lớp 8 có diện phân bố gặp trong tất

Lớp 8 có diện phân bố gặp trong tất cả các hố khoan, nằm dưới dưới lớp 5, lớp 6 và lớp 7. Chiều dày của lớp chưa xác định vì các hố khoan đến độ sâu nghiên cứu chưa gặp đáy lớp này. Thành phần của lớp là đá vôi màu xám, xám trắng. Đá bị nứt nẻ mạnh và phong hóa trung bình.
Đặc điểm của lớp là đá gốc hầu như còn tươi, bị nứt nẻ mạnh đến trung bình, phong hóa trung bình đến nhẹ. Độ bền cơ học của khối đá có suy giảm so với đá nguyên khối nhiều
Trong lớp đá này bắt gặp tại một số khu vực đá vôi bị Karst hóa (HK8 và HK10) với bề dày từ 1,82m (HK8) và 1,93m (HK10). Cao độ đỉnh hang Karst là -44,20m (HK8) và -37,01m (HK10), cao độ đáy hang Karst là –45,36m (HK8) và -38,94m (HK10). Hang được lấp nhét bằng sét pha, dăm sạn lẫn sét trạng thái dẻo chảy dẻo mềm.

Grade 8 have an occurrence in all the boreholes, located under the bottom grade 5, grade 6 and grade 7. The thickness of the layer is not yet determined for boreholes to a depth of research have yet to see the bottom of this class. The composition of the layers of gray limestone, grey and white. The rock was weathered and chapped.Characteristics of the class was the original almost fresh, being strong to moderate fissures, weathering moderate to light. Mechanical durability of stone blocks have declined compared to monolithic lotIn rocks encountered in some areas limestones being Karst (HK8 and HK10) with thickness from 1, 1,640 (HK8) and 1, 93m (HK10). Top Karst cave is -44, 20 m (HK8) and -37, 01m (HK10), Karst cave floor elevation is-45, 36 m (HK8) and -38, 94m (HK10). The cave was filled with rubble, clay hotel is tucked and flexible flow state soft plastic clay.

8th grade distribution covers encountered in all drill holes, located under the bottom layer 5, grades 6 and 7. The thickness of the layer of undetermined because the borehole to a depth of research have not seen the bottom of this layer. The composition of the layers of gray limestone, gray and white. Rock was fractured and weathered average.
Features of the class is almost fresh bedrock, cracks strong to moderate, moderate to mild weathered. Mechanical strength of the rock mass has decline compared to monolithic many
caught in the rock layers in some areas limestone Karst chemical equipment (HK8 and HK10) with a thickness of 1,82m (HK8) and 1, 93m (HK10). Karst caves high peak is -44,20m (HK8) and -37,01m (HK10), Karst cave bottom elevation is -45,36m (HK8) and -38,94m (HK10). Hang been stuffed with clay fill, gravel and clay flowing in soft plastic state.

Grade 8 has surface distribution in all drill pits in the following five, grade six and grade seven. The thick layers of the afternoon are not defined because the study of the depth of the hole has not been seen in this category. Stone by wind power and crack average.The class is characterized by the fact that the original stones are almost fresh, the average of cracks is strong, the wind is light to medium. Mechanical durability decreased compared to the carrier with many stone elementsIn this discovery of rocks in some areas of limestone Karst (HK8 and hK10) and thickness (from 1,82m HK8) and 1,93m (hK10). Peak height is 44,20m Karst Cave (HK8) - and (- 37,01m hK10), height (HK8 Karst cave bottom is - 45,36m 38,94m) and - (hK10). Fill in the hole with lightning and lightning method Hotel soft plastic flow state.
