摘要
单县能源公司根据煤层地质条件选取了合适的注水工艺及注水参数,对大倾角大采高三软煤层综采工作面的煤壁进行超前注水,板结了松软的煤体,有效控制了煤壁片帮和梁端冒落现象,达到了较好的综采面降尘效果,节约了高分子加固材料费用。
Shanxian energy company selects the injection process and injection parameters based on the geological conditions of coal seam, advanced water injection in coal wall of the large dip angle mining soft coal seam fully mechanized coal mining face with large mining height, harden the soft coal body, control the coal wall spalling and beam falling phenomenon effectively, achieve the better dustfall effect in fully mechanized coal mining face, and save the cost of polymer reinforced materials.
