矿井地质因素对煤与瓦斯突出的分布规律影响很大,对准确预测突出区至关重要。简述了九里山矿井地质构造特征及煤与瓦斯突出概况,详细分析了该矿煤与瓦斯突出与煤层厚度及变化、断层构造、地下水活动情况等地质因素之间的关系,得出影响九里山矿煤与瓦斯突出的主要地质因素,采用了低临界值与等性块段叠加法预测了突出危险区,为以后采取有效防突措施奠定了基础。
Mine geological factors have a great influence on the distribution of coal and gas outburst, and it is very important to accurately predict the outburst area. This paper briefly describes the geologic structure characteristics of coal mines and the general situation of coal and gas outburst in Jiulishan Mine, analyzes the relationship between the coal and gas outburst and the geological factors such as coal seam thickness and variation, fault structure and groundwater activity in detail, The main geologic factors of mine coal and gas outburst are predicted by using the method of low threshold and superposition of block segments to predict the prominent danger zone, which lays the foundation for effective measures to prevent outburst.
