地质构造复杂地段岩巷掘进过断层技术实践

地质构造是影响矿井安全生产的重要因素之一,在断层构造发育、落差大、断层带破碎的条件下,其对巷道掘进影响尤为突出。在综合分析鹤煤十矿15采区地质及水文地质复杂条件的基础上,通过采取物探先行,钻探验证,技术保障施工技术,及时调整了支护方式。实践证明,该施工技术保证了岩巷掘进顺利穿过断层。

Practice on Technology of Rock Roadway Drivage Passing Through the Fault Under Complex Geological Conditions

The geological structure is an important factor which impacts safety production of coal mine.The influence to the drivage of roadways is more obvious especially in the conditions of fault structures developing,high drop,fratured faults.Based on the analysis on the complex geological and hydraulic conditions in No.15 Mining Area of Hebi No.10 Coal Mine,the supporting way was adjusted in time through the construction technology as follows:geophysical exploration serves as forerunner,drilling inspection later,...
