Exploration of Xiping Coal Mine in Hezhang County, Bijie Prefecture, Guizhou Province

(1) Overview

Xiping Coal Mine is located about 2 kilometers west of Hezhang County, and its administrative division is under the jurisdiction of Shuangping Yi, Miao and Luozhou townships in Hezhang County, with an area of about 18.81 square kilometers. From August, 28 to September, 211, exploration was carried out. The mineral of exploration was coal mine, and the degree of work was exploration.

(2) Description of achievements

The main minable coal seam in the mining area is the fourth section (3) of Xuanwei Formation, and the following first and second sections do not contain minable coal seam; In addition to the designed three-layer minable seam, there is also a layer of local minable seam; The original designed three-layer minable coal seam is not recoverable locally; The depth of each minable coal seam in the axis of syncline is slightly shallower than the design, and the number of coal seams in the north-west side of syncline decreases and the thickness becomes thinner.

through calculation, the total amount of coal resources seized in this coal mine exploration area is 14 million tons. Among them, (331) resources are 29 million tons, accounting for 27.65%; (332) The resource is 42 million tons, accounting for 4.17%; The (331+332) resource is 71 million tons, accounting for 67.82%, and the (333) resource is 34 million tons, and the resource reserves have passed the review.

(3) Brief process of achievement

In August p>28, exploration construction was officially started, and all the field work was completed by mid-May 211. * * Workload completed: 1∶1 geological mapping of 4 square kilometers, drilling of 2,998 meters, cleaning of 25 meters of old adit, trench exploration of 8 cubic meters, taking 31 pieces of coal core sample and 1 piece of coal seam sample.
