Xixinzhuang town

Xixinzhuang town is located in the Rocky Mountain Area on the southwest of Xiaoyi City, 35 km away from Xincheng City, between 37002 / N and 111030 / E. It is adjacent to Zhuangli, Sanhekou and HeJiazhuang in Zhupu town in the East, muguaqu, Sunyi and Yanzhuang in Lingshi County in the south, Dongling and hengluo villages in taohongpo town in Jiaokou County in the west, Jiaochang, Hebei, Liuwan and Zhongjiashan villages in Yangquanqu town in the north, and guojiazhang and Wenquan villages in Jiaokou County in the northwest. It has a total area of 72.94 square kilometers, 41270 mu of arable land, 36 village committees, 4296 households and 15606 people (2017). The Heling River and Xiquan River, which flow from northwest to Southeast, divide the town into three mountains and two gullies. Arranged in a crisscross pattern, the Wutong line, which is built along the river, is located on the west side of the kiln (crossing the kiln to the west of the junction), the West Yu line (West Xinzhuang to Yulin), the west line (Wu Tong to the West Xinzhuang), and the Xiao Wu line across the town, and the "village and village" oil road leading to the villages. The underground resources of the town are mainly coal, with abundant reserves and excellent coal quality. The climate is relatively cold, and the frost free period is only 140-150 days. The main crops are corn, sorghum, millet, beans, potatoes and so on.

structure

Structure refers to geological structure. The geological structure in Xixinzhuang town is basically NE and Se monoclinic structure, and the monoclinic structure is developed with secondary basin like folds and gentle slope like ups and downs. According to the results of satellite aerial survey and drilling, the larger scale is facing the TA anticline, the southern end is facing the west of TA village, and the axis is 40 to the north

landforms

The geographical location of Xixinzhuang town is between 3702 N and 11130 e. the whole terrain is high in the northwest and low in the southeast, showing a NE trend. The total area of the town is 72.94 square kilometers, equivalent to 113080 mu. The commanding height of the territory is dongzhuangyan, 1157 meters above sea level, followed by Fenghuangling, 1100 meters above sea level. The whole area is a typical hilly and rocky mountainous area. After the Paleozoic, the Luliang mountains rose relatively. In the later stage, due to the accumulation of Cenozoic loose rocks, under the influence of Himalayan movement, the crust continued to rise slowly, the erosion base area decreased relatively, and the Quaternary loess materials were widely accumulated. Due to the loose structure of loess, rich in calcium, the anti erosion ability was very weak. Under the long-term effect of surface water, the loess was eroded The frequent accumulation makes the erosive gullies develop rapidly and incise strongly, especially with the increasing of modern cultivation index and the increasing of surface runoff, which makes the underlying bedrock bare. Numerous feather shaped gullies with a depth of 30-80 meters are formed on the ground, that is, the ridge is narrow and long, the hill is hilly, the gully is stepped, and the gully bottom is V-shaped, which varies with the degree of erosion.

hydrology

Hydrology is also called water resources.

rivers

There are two main rivers in Xixinzhuang Town, namely Xiquan River and Heling river. Xiquan river originates from Fujiazhuang, Wenquan Township, Jiaokou County, flows southeast to Xiamen village, Xiamen town, Lingshi County, and joins Fenhe River. The section from xiqigou to Dawangzhuang is 1 km long in Xixinzhuang town. The drainage area is 26.1 square kilometers, and the maximum peak discharge is 400 m3 / s. Heling river originates from Xixinzhuang village, flows southeast to penzipo, joins wangcaibao River, flows southeast to taokouyuan, joins Luzi River, flows southeast to Yanzhuang, and enters Lingshi County, with a length of 16.5 km.

reservoir

In the early 1970s, wangcaibao village organized the construction to build a small reservoir with a capacity of 1 million cubic meters. Later, it was abandoned and turned into a dam due to silt.

vegetation

The distribution range of vegetation community and species in Xixinzhuang town is complex. Generally, in the Rocky Mountains above 1000 meters above sea level, the natural vegetation is dominated by shrub and grass plants, followed by secondary forest plants. Its coverage is about 30%, and the plants are mainly shrub birch species. The distribution of shrubs and grasses is lower than 1000 meters above sea level, and the grasses are mixed with shrubs. The plants and plants are: Carex, Leymus chinensis, Kobresia, huangbaicao, yegucao, weilingcai, waitoucao, Vicia sativa, chrysanthemum indicum, Stipa, polygonatum odoratum, Dianthus, Lilu, etc. Shrub plants are: Lespedeza, vinegar willow, hazelnut, Rosa davurica, etc.

In the area occupied by farmland, the natural vegetation is xerophyte community only in the non cultivated land and farmland slope. In the sunny slope with poor water condition, herbaceous plant communities are dominant, such as Leymus chinensis, Artemisia argyi, Pennisetum, etc.; in the sunny slope with good water condition, tiegan and weilingcai are dominant; in the gully slope with east-west direction, sparse grass shrub mixed plant communities are common, such as niujizi, Chaenomeles Chaenomeles, purple pea, Artemisia capillaris, etc.; in the steep wall or cliff, sour jujube, wolfberry and Huperzia are common Some shrub plants, such as Jizi, Xanthoceras sorbifolia, and some herbaceous plants. In addition, there are 9134.10 mu of natural grassland and artificial grassland in the town.

mineral resources

Minefield

The main mineral resources of Xixinzhuang town are coal, and there are four minefields in the town. Wangcaibao minefield, with a total thickness of 118m, coal seam thickness of 8.96m and coal content of 7.09%. The thickness of Taiyuan formation is 80 meters, the thickness of coal seam is 7.61 meters, and the coal content is 3.55%. In Heling mine field, the total stratum thickness is 122m, the coal seam thickness is 8.3m, and the coal content is 6.2%. The thickness of Taiyuan formation is 80 meters, the thickness of coal seam is 7.42 meters, and the coal content is 9.28%; the thickness of Shanxi formation is 42 meters, the thickness of coal seam is 0.88 meters, and the coal content is 2.1%. Xinzhuang minefield has a total stratum thickness of 121 meters, coal seam thickness of 9.8 meters and coal content of 8.4%. Taiyuan formation is 80 meters thick, coal seam thickness of 8.85 meters and coal content of 11.06%; Shanxi formation is 41 meters thick, coal seam thickness of 0.95 meters and coal content of 2.32%. The thickness of Taiyuan Formation in nanshangzhuang minefield is 80 meters, the thickness of coal seam is 7.2 meters, and the coal content is 9%.

Coal quality

The 11 and 9 coal seams of the four minefields in Xixinzhuang town are all fat coal. The change rule of sulfur content in each coal seam is that Taiyuan formation is higher than Shanxi formation. Taiyuan Formation coal seam is high sulfur coal, so it is not suitable for coking alone. Shanxi Formation coal seam is medium and low sulfur coal, with organic content of 0.14-0.91%. After washing, the total sulfur content is less than 1%, which meets the requirements of coking. Its ash content is between 44-46, and the gas content in each mine field is low, which is grade I
