Discovery and Geological Characteristics of Tong Zhe Coalfield in Henan Province

The discovery of Tong Zhe coalfield and its geological characteristics are as follows:

1. The discovery of Tong Zhe coalfield in Henan Province is based on the joint work of several geological exploration funds (circulating funds) projects in Henan Province. These projects include "coal survey in the west of Suixian county, Henan province", "Huxiang coal survey in Shangqiu area, Henan province", "seismic survey and resource prospect evaluation in Tongxu uplift and Kaifeng depression area, Henan province".

2. The exploration work lasted from June, 20 1 1 year to February, 20 13, during which the 2D seismic 13 1685 physical point was completed and the hole 173 was drilled. In terms of prospecting, this coalfield has achieved a major breakthrough in deep prospecting in eastern Henan.

3.* * The estimated coal seam resources in Suixian West Coal Survey Area and Huxiang Coal Survey Area 1 (333)+(334) are19917.38 million tons, of which (333) resources are 2,792.84 million tons and (334) resources are. Among them, the buried depth is 1.500m, the shallow resources are 1.83856 million tons, and the natural coke resources are 200.59 million tons, reaching the scale of large coalfields.

4. The survey area predicts that the resources of the second floor 1 coal seam (334) are 8,277.76 million tons. The estimated coalbed methane resources in the whole coalfield are 108246 billion cubic meters. Tong Zhe coalfield is located in the underground of eastern Henan plain, which is a large hidden coalfield. It is characterized by rich coal resources and deep burial depth, generally below 800 meters.

The departments responsible for Tongtuo coal exploration are as follows:

1, many departments are responsible for the work in coal exploration, Tong Zhe. First of all, Henan Coal Geological Survey and Research Institute is the main unit in charge of coal geological exploration, responsible for coal geological exploration, resource evaluation and coalfield development scheme design.

2. The Fourth Research Institute of Henan Bureau of Geology and Mineral Exploration and Development also participated in the exploration of Tong Zhe coalfield. They are responsible for the investigation, evaluation and reserve estimation of mineral resources, and provide scientific basis for coal field development.

3. Henan Academy of Land and Resources Science, Geophysical Survey Team of Henan Coalfield Geology Bureau, Henan Airborne Geophysical Remote Sensing Center and other units also participated in the exploration of Tong Zhe Coalfield. They used advanced scientific and technological means such as geophysical exploration and remote sensing to conduct detailed exploration and analysis of the geological conditions of the coalfield, providing technical support for the development of the coalfield.

4. During the exploration, these departments cooperated closely and completed the exploration of Tong Zhe coalfield. They not only know the geological conditions of the coalfield in detail, but also comprehensively evaluate the coal resources and development conditions. The completion of these works has provided important scientific basis and technical support for the development of Tong Zhe coalfield.
