厚泥岩伪顶条件下综掘架棚巷道开门拐弯及调向准确性控制研究OA
Research and application of the opening and turning accuracy control of heading roadway with shed under the condition of thick mudstone false roof
3下1101外切所处南十一采区地质构造较为复杂，巷道使用综掘机进行掘进施工，采取架棚方式进行支护，这就使得巷道在开门、拐弯、调向等特殊作业环节施工难度较大。对厚泥岩伪顶条件下如何准确控制综掘架棚巷道开门拐弯及调向进行研究，将研究成果进行实践应用，取得了较好的效果。
the South eleven mining area geological structure is more complex 3 1101 outer cross-cut locates the, the shed supporting form was taken , and the fully mechanized excavation was used to construct, which makes the roadway opening , turning and adjusting special operations be difficulty, the technical scheme how to accurately control the heading roadway turning and opening the under the thick mudstone false roof condition was studied, the practica…查看全部>>
