| 摘 要： | 阐述了断裂构造对煤与瓦斯突出的控制和不同构造部位瓦斯突出的差异性。因煤层围岩性质的不同，地质构造的差异，瓦斯突出的地段和危险性也不一样。主控断裂的作用形成了不同的构造应力分区，从而导致瓦斯不同程度地聚积与泄散，决定着煤与瓦斯突出的强度、密度的分区分带性。这些研究成果对利民矿井各采区瓦斯突出危险性的预测，具有现实意义。

ELEMENTARY STUDY ON FRACTURE STRUCTURE CONTROLLING COAL & GAS OUTBURST IN LIMIN MINE |
| |
| Abstract: | This paper has emphatically elaborated fracture structural factors controlling coal & gas ,,outburstmaking otherness of outburst danger on varied structural position. Meanwhilethe country ,rock property of coal seam is differentthere are not alike growth of the geological structures. The magnitude and position of fatalness of coal & gas outburst are also different. The main function of ,fracture structures has formed different structural stress blocksthereby leading to varying on ,,accumulation and release of gas and resulting in blocks and zones of intensitydensity of coal & gas outburst. All these research achievements will play an important realistic role in predicting fatalness of coal & gas outburst in various mining areas of Limin mine. |
