大平矿综放工作面水库下开采探析
|
摘要
在充分了解国内外水体下采煤研究现状的基础上,从水体下采煤的特点出发,根据N1N4综放工作面地表水体特征、上覆岩层的赋存状态及煤层埋藏条件,通过分析大平矿覆岩破坏规律及N1S1综放工作面水库下开采部分成果,得出导水裂隙带高度,按照《"三下"开采规程》要求计算出防水煤岩柱厚度,经验证,N1N4综放工作面水下开采是安全可靠的。根据煤层的赋存结构和大平矿生产实践,列出自然分层综放、人工分层综放和综放全采3种开采方案,通过理论和实践验证,在N1N4综放工作面采用自然分层综放开采是安全可靠的。
Based on the full understanding of the research status of coal mining under water bodies at home and abroad,based on the characteristics of coal mining under water bodies,according to the surface water features of the N1 N4 fully mechanized caving face,the occurrence of overlying strata and the burial conditions of coal seams,through the analysis of the overburden rock failure law of Daping mine and the results of the exploitation under the N1 S1 fully mechanized caving face reservoir,the height of the water guiding fracture zone is obtained,and the thickness of the waterproof coal pillar is calculated according to the requirements of the"three down"mining regulations,the N1 N4 fully mechanized caving face has been verified that underwater mining is safe and reliable. According to the occurrence structure of coal seam and the production practice of Daping Mine,the three mining schemes of natural stratified fully mechanized caving,artificial stratified fully mechanized caving and fully mechanized caving are listed,through theoretical and practical verification,natural points are adopted in the N1 N4 fully mechanized caving face,full-bore mining is safe and reliable.
