陈四楼煤矿2513工作面地质条件复杂,掘进过程中多次分段揭露火成岩带,严重影响了正常的掘进施工。针对火成岩入侵特性,经过现场不断的施工探索,研究出降低炮眼深度、改变施工组织的短掘短支施工及管理技术,在过火成岩带掘进中应用效果明显,提高了掘进进尺,保证了采掘生产的正常接替。
Chen Silou Coal Mine 2513 face complex geological conditions, digging several times during the excavation of igneous rocks, seriously affecting the normal excavation. Aiming at the characteristics of igneous intrusion, through continuous construction and exploration on the spot, the research on the construction and management of dug short and short branches which can reduce the depth of borehole and change the construction organization has been made. The application effect is obvious in the excavation of over igneous rock zone, The normal succession.
