Xinggong Coalfield ()

Xinggong Coalfield spans Gongyi, Xingyang, Mixian, Xinzheng, Zhengzhou and other counties and cities, and belongs to Carboniferous-Permian coalfield, with * * * three layers of recoverable and partially recoverable coal, namely 1, 17 and 2 1 coal, mainly anthracite and a small amount of lean coal.

According to the records of the Northern Wei Dynasty (AD 386-534) geographer Li Daoyuan's Notes on Water Classics, Notes on Water in Zhuozhang and Biography of the Western Regions, as well as the discovery of the iron smelting site in Tieshenggou, Gongyi and Guxing Town, Zhengzhou City, it can be known that coal and iron were mined in Gongyi and Xingyang in the Western Han Dynasty.

19 16, the Swedes wrote "Coalfield and Coal Mining in Henan", which shows that there are many coal mines in Xingyang Coalfield although there is no investigation. There are many coal mines in Gongxian coalfield, all of which are brittle anthracite.

193 1 In August, Cui Buying investigated the coal mines in Cuimiao area of Xingyang, and wrote "Investigation of travertine coal mines in Xingyang County, Henan Province", believing that the coal mines in this area belong to Permian semi-anthracite coal.

During the period of 1934, Wang Jingzun inspected Gongxian coalfield and wrote the Report on Geology and Mineral Resources of Southeast Township of Gongxian County and Northwest Township of Mixian County, Henan Province, and thought that this area was high-quality anthracite.

During the period of 1936, Cao Shilu made a geological survey in Surabaya and wrote mineral reports in Surabaya, Yanshi, Dengfeng, Luoyang and Linru counties.

1947 1 month to 1948 1 month, where the Henan Geological Survey is located, drilled holes in Donglu Village, Laozipo and Shi Peng of Donglu Coal Mine in Xingyang County 1 hole, with a total footage of 489.5 meters. According to 1948 Coal Mine Records of Henan Province compiled by this drilling, Xingyanggong was described.

1A Brief Report on Minerals in Gongxian County, Xingyun, written in August, 950, describes the general situation of coal mines, iron mines and bauxite mines, and points out that coal is the main mineral in Gongxian County, and aluminum mines can be concerned. Ni Yuanjiang, chief engineer of Central South Coalfield Geological Survey Bureau, wrote the report of coalfield geological survey in Xing, Gong, Yan and Luo areas, and calculated the reserves: the area is 92.8 million tons; Xiaoguan District157.6 million tons; The village area is 64 million tons.

1953, Cao Shilu explored Xinggong coalfield again, and it is estimated that the coalfield reserves have been greatly improved compared with before, reaching about 800 million tons.

During the period of 1958, the geophysical exploration team (technical director Zhang Daogang) and 127 geological exploration team (technical director Lu Ping) of the Central South Coalfield Geological Bureau carried out the general survey and prospecting work combining electrical exploration and drilling, and submitted the Report on Electrical Exploration in Xingyang-Zhongmou Area and the Report on Zhengzhou-Luoyang Comprehensive Survey.

1In April, 959, Henan Coalfield Geology Bureau 103 Team (technical director Zhang Wenyu) compiled the geological data of Xingyang, Gongxian and Yanshi Longmen coalfields, and calculated the reserves of Xinggong District13.93 million tons.

In September, 1960, Henan Coalfield Geology Bureau 105 team (technical director Ge Xia) compiled the Geological Report and General Survey Design for Prospecting in Taihang Mountain Area of Xinggong Coalfield, and thought that Baiyuling Graben might be a large landslide.

1 September, 1968, the exploration team of zhongnan coalfield geological bureau 127 (technical director Zhang) compiled the report on coal mine exploration geology in Xingyang mining area1,No.2 and No.3 coalfields. In view of the fact that Xuzhuang fault is located between Xuzhuanggou and Cui Miao in the mine field, Triassic strata in all boreholes are in contact with coal measures strata, and the fault dip angle is about 20. Because this kind of fault mostly occurs on the second 1 coal in the main coal seam, generally the second 1 coal is not destroyed, so it is named "epidermal fault". At the same time, 125 exploration team (technical director Zhang Wenyu) compiled the final report of coal mine geological exploration in Lisan (Hongwei) exploration area of Xingyang coalfield, which was reduced to detailed investigation due to too much coreless drilling and poor quality.

The Third Geological Team of Henan Coalfield Geology Company (Chief Engineer Zhu) made supplementary exploration of Xinggong Coalfield, and successively submitted supplementary exploration geological reports of Dayugou (former No.1 minefield), Gushan (former No.3 minefield) and Shenhe minefield from 1982 to 1985.

1In August, 985, Henan Coalfield Geological Consulting Center sorted out the original geological data of this area and compiled the Geological Report of Zhengjiao Gaomiao Small Well in Xinggong Coalfield.

By the end of 199 1, the proven coal reserves in xinggong coalfield were 897 million tons, and the retained reserves were 865,438+1100 million tons. The mine fields that have built wells include Xuzhuang Coal Mine, Dayugou, Gushan and Wanghe, with an annual output of more than 2 million tons of raw coal.
