Abstract:The paper has analyzed some geological type classification issues in the existing “ Specifications for Coalmine Geological Works” ( hereafter abbreviated as “ the specifications” ) ꎬ then compared the similarities and differences between the specifications and coalmine geological type classification reportꎬ coalmine geological reportꎬ as well as studied issues in coalmine gas type classification indices. Combined with the “ Mine Geological Regulations” and other related existing technical regulations and standards have pointed out that the outstanding issues such as relationship among geological type classification in the specifications and coalmine construction and production geological reports have been artificially complicatedꎻ coalmine geological type assessment uniqueness and statute for lim ̄ itation conflictedꎻ coal seam gas content as an index in gas type classification unreasonable and intentionality absence in relationship between coalmine geological condition classification and coalmine production safety etc. Thus we have suggested that the coalmine geo ̄ logical type classification report should be incorporated into coalmine construction and production geological reportsꎻ categorically iden ̄ tified geological type classification should take the coalmine succession area as the assessment targetꎻ indices for defining coalmine gas type should be mainly gas gradingꎬ supplemented with gas pressure and gas content. Finally the paper put forward a “ four categories and ten types” coalmine gas type classification scheme. Keywords:Coalmine geologyꎻ Geological typeꎻ Gas contentꎻ “ four categories and ten types”
摘 要:针对分析了现行«煤矿地质工作规定»中地质类型划分问题ꎬ通过分析煤矿地质类型划分报告和煤矿地质 报告的异同点、煤矿瓦斯类型划分指标、及其地质类型划分对煤矿地质、煤矿设计、安全生产的影响ꎬ结合« 矿井地 质规程»等相关现行技术规定及标准ꎬ指出«煤矿地质工作规定» 中地质类型划分与煤矿( 建井、生产) 地质报告关 系人为复杂化、煤矿地质类型评定在空间和时效性存在矛盾、煤层瓦斯含量作为划分瓦斯类型指标不合理以及煤 矿地质条件分类与煤矿生产安全相联系的目的性缺失等突出问题ꎮ 建议把煤矿地质类型划分报告并入煤矿建井 及生产地质报告之中ꎻ明确“ 地质类型划分” 以煤矿接续区为评价对象ꎻ提出以矿井瓦斯等级为主、瓦斯压力及瓦斯 含量为补充作为煤矿瓦斯类型划分指标ꎻ并给出了“ 四类十型” 煤矿地质类型划分方案ꎮ 关键词:煤矿地质ꎻ地质类型ꎻ瓦斯含量ꎻ四类十型 中图分类号:P618������ 11 文献标识码:A
