火成岩带短掘短支施工组织技术研究与应用

Research and Application of Igneous Rock with Short Dig Short Construction Technology

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。

Complicated geological conditions of Chensilou coal mine 2513 working face,driving multiple segment in the process of igneous rock band, seriously affected the normal construction. For igneous rock intrusion characteristics, after the scene construction exploration, developed to reduce the depth of the hole, change the short dig short branch of the construction organization construction and management techniques,in igneous rock band during the application effect is obvious, increase the tunneling footage, ensure the mining production.
