大埋深工作面“110”工法开采技术研究与应用

Research and Application of "110" Construction Method Mining Technology for Deep Burial Working Face

针对福城煤矿1906S工作面运输巷留巷问题,若沿用过去传统的技术做法,不能有效地组织生产,缓解矿井生产接续紧张状况。基于110工法,研究提出了"1906S工作面运输巷切顶卸压无煤柱自成巷"开采方案。施工期间,严格落实前期补强支护和后维护支护措施,控制了顶板下沉量及巷道变形量,保证了留巷效果,通过本开采方案的实施,1906S工作面运输巷按计划成功完成留巷1100m。

In order to solve the problem of the retained roadways in the transportation lane of 1906S in Fucheng Coal Mine,new ways must be proposed.If the traditional technical methods are used,the production can not be effectively organized to relieve the tension of the mine production.Based on the 110 construction method,this paper proposes the mining plan of"roof-cutting pressure relief no coal pillar self-forming roadway in the transportation lane of 1906S working face".During the period of construction,we strictly implement the early period reinforcing supporting and later period maintenance support measures,and control the subsidence and deformation of roadway roof,which guarantees the effect,for through this mining plan,the 1906 s face transportation lane successfully completes the 1100 m,as it is planned.
