摘要:
以鹤岗煤田—兴山井田地质构造演化为基础,运用瓦斯地质理论、构造逐级控制理论,通过综合分析兴山井田地质构造、瓦斯地质参数、瓦斯涌出参数,着重分析兴山煤矿27#煤层瓦斯赋存规律及瓦斯赋存影响因素。通过分析可得,矿井断层、埋藏深度以及顶底板岩性是影响井田瓦斯含量的主要因素,并得出27#煤层瓦斯含量与煤层埋深关系较为密切,随着煤层埋深的增大,瓦斯含量也不断增大。变化梯度为埋藏深度每增加100 m,瓦斯含量增加2.46 m3/t。

Abstract: By using the gas geological theory, control theory constructed progressively in Hegang coalfield, Xingshan mine geological tectonic evolution. Through a comprehensive analysis of the geological structure of Xingshan coal, gas geological parameters and parameters of gas emission, we re-searched the gas-geology regularity and the major influence factors of No. 27 seam in Xingshan coal mine. Comprehensive analysis shows that mine faults, burial depth, and roof and floor lithology are the main factors affecting the gas occurrence. The relationship of gas content of 27# coal bed and the coal seam buried depth is closer. Overall, along with the increase of depth of coal seam, gas content increases. Gradient change is that when buried depth increases 100 m, gas content increases 2.46 m3/t.
