Hebei Lulong Lugao Mountain oil shale contains the evaluation of resources in the mining area

Lulong Luwei Mountain oil shale contains the mining area near Luwei Mountain Village, Dongfeng Township, Qian'an County, Hebei. The geographical location is: 118 ° 51 ～ 119 ° 02 east longitude; 40 ° ～ 40 ° 08 north latitude, which belongs to the geographical environment of the hills. About 30 km away from the county town, the transportation is convenient. The highway passes through the Qian'an, Liujiaying, Qian'an County Town and the Jingha Railway Yixian County Station.
. Geological background
(1) Constructing characteristics
This containing mining areas is generally single -to -be -oblique structure, which is nw, tilted to SW or SE, and the inclination angle is 50 ° ~ 80 °. Most of the development of the mining area is mostly the backstracks near the east and west. The main faults are: F1 reverse the fault, located in the middle of the mining area, standing east -west, squeezing in the local area, and S -shaped scratching in the fault. The F3 decisive layer is located in the northern part of the mining area. The Jurassic and foggy mountain group is contacted with the fogmine mountain group. The north and west are located in the northern part of the mining area.
(2) Stranger characteristics
The mining area mainly revealed the previous Zhendan film, the zhen Dan system, the lime limestone and the middle -generation Jurassic Luga Mountain group sand shale. From the old to the new narrative as follows:
1. The former Zhendan system
The main body of the Zhendan is the oblique long tablet of Heiyunmu.
2. The Zhendan Fog Mountain Group (Z2W)
The Zhendan Fog Mountain Group is mainly based on the white Yunyan clip.
3. The Jurassic Lugar Mountain Group
The upper part of the strata is the white clouds fragrance section, which is mainly light gray thick vermiculite arges; Section, gray -white thick -like quartz sandstone clamp the thin layer of oil shale. The lower part is the second layer of oil -containing sandy shale section, Baiyun rock and Baiyun fragrant section, and vermiculite angle segment.
4. New Near
The new system is mainly slope residual accumulation, and the thickness is not large.
. The characteristics of oil shale
(1) Oil shale characteristics
The oil shale in this area is mainly black and gray -brown. The ore is dark brown dense and thin -shaped, thinned pages, and the strip marks are brown. After the weathering, it is gray clay. The hammer has oily odor, combustion. After sintering , Hardness 3 to 4, real weight 1.70 ~ 2.40T/m3, oil content 4.28%to 13.23%(Figure 5-31), the oil shale heat of the area is high, 3.87mJ/kg.
(2) Oil shale formation environment analysis
In the survey data, we can see that the oil shale in the mining area has changed a lot, and the thickness of the thickness is very large. No fossil relics were found in the area. Organic substances in the ore are mainly algae and mud fragments, and the oil shale is made of mud in the lake basin.
Figure 5-31 Lulong Luweishan oil shale contains the thickness of the oil shale thickness and oil content of the mining area. In the upper Jurassic, there are two layers of oil -containing shale, all of which belong to the Jurassic Lugar Mountain Group. The mine layer is mainly distributed west of the exploration line, and the Ⅰ exploration line is 1400m east. Although there is still an extension in the west, it is cut by the F1 fault and is a hidden ore body. Although the surface on the east of the exploration line has this level, the deep part of the deep part of the CK19 crushing belt is affected by the F1 and F2 faults, which has no industrial value (Figure 5-32).
. Evaluation of oil shale resource
(1) Analysis of geological work level
The oil shale in this area was used by local residents as fuel in 1940. In the old pit mouth. The local mining was restored in 1958, but due to the poor quality, it stopped mining in July. In 1985, according to the crowd of mining clues, the census team went to the area to carry out census to find mining work, and carried out surface exposure, samples, and 1: 20000 topographical geological briefing drawing work. The preliminary estimated reserves were 6 million t. In 1959, according to the urgent needs of local industries, geological work was transferred from census to investigation. By the end of 1960, the final exploration report was submitted.
The exploration work reaches the degree of detailed investigation. Control A2 -level reserves with 250 × 250M exploration mesh, and 400 × 200M control B -level reserves. The A2 -level reserves are 600,000 t, the B -level reserves are 3.84 million t, and the C1 C2 level reserves are 5.62 million t.
(2) Resource evaluation
The resource evaluation results show that the resource reserves of the oil shale in the mining area are 6.15 million t, and the resource reserves are 6.15 million t. The reserves of the technology recoverable resource are 3.69 million T, and the reserves of the technology recoverable resource can be found that the technology recovered resource reserves are 3.69 million T. The reserves of shale oil resources are 420,000 T, the resource reserves are 420,000 T, the technology can be recovered by 250,000 T, and the technical resource reserves are 250,000 T. The reserves of shale oil recyclable resource reserves of 190,000 T, shale oil found that recyclable resource reserves of 190,000 T. The area belongs to small oil shale mines.
