(1) Overview

The climate in this area belongs to continental semi-arid area with insufficient humidity. The annual rainfall is mainly affected by spring, autumn and winter winds, and there is less rain. Gullies and ridges in the whole region alternate with each other, criss-crossing. Gullies and valleys are mostly V-shaped, and ridges are mostly fish ridges and steamed buns, showing the landform of eroded low mountains and hills.

From 20 10 to 20 1 1, the resources and environment investigation center of Henan Coalfield Geology Bureau carried out exploration work, and the exploration mineral was limestone for cement. The survey work level was 2140,000 yuan.

(2) Description of results

Each section in the coal seam (body) sample in this mining area meets the requirements of industrial indicators. The highest content of CaO in a single sample is 55.52%, with an average of 50.49%. The content of MgO is generally between 0.5% and 3%, the minimum content of a single sample is 0.43%, and the average content is 1.87%.

The total coal seam (body) resources are estimated to be (333) 9 19 1 10,000 tons. All the ores in this mining area are first-class products. Resource reserves have not been reviewed.
