Research on bolt-cable reducing span support technology in large span roadway of fully-mechanized coal

Zhu Yongjian,Luo Yixin,Zhang Daobing

Strategic Study of CAE 2010, Volume 12, Issue 3, Pages 51-55

Abstract:

Aiming at the locale facts of difficult roof controlling for large span gateway of fully-mechanized coal faces, based on analysis of the influence factors of monolayer strata stability, the numerical simulation soft UDEC3.0 is employed to deeply research influence factors and changing rules of roof stability of the gateway which is composed by some monolayer strata. A new supporting idea of reducing span supporting function by bolts cooperating with anchor cables is brought forward by disposing anchor cables at the appropriate locations, the traditional supporting theory such as suspensory and compounding beam (arch) are still operated at the same time. A good result is achieved after the new supporting idea is applied in the large span gateway of Bulianta Colliery in Shendong diggings.

Classification Model and Its Application of Stability of Roadway Driving Along Next Goaf for Fully-mechanized

Zhu Chuanqu,Wang Weijun,Shi Shiliang

Strategic Study of CAE 2006, Volume 8, Issue 3, Pages 35-38

Abstract:

The stability of roadway driving along next goaf for fully-mechanized caving face is syntheticallydepth, joint and crack of surrounding rock, mining operation, top coal thickness, width of pillar and roadwayexperience and observation data, the subordination functions of the factors influencing the stability of roadwayaccurate and reliable, and plays an important part in the support design, construction and management of roadway

Theory and practice of integrated pillarless coal production and methane extraction in multiseams of low permeability

Yuan liang

Strategic Study of CAE 2009, Volume 11, Issue 5, Pages 72-80

Abstract:

This thesis, based on innovations and practices of methane drainage in multiseams of low permeability and complicated geology in Huainan mining district, systematically describes theories and key technologies of integrated pillarless coal production and methane extraction with "Y" type ventilation system in multiseams of low permeability. Through analyses of deformation, fracturing and failure of rocks around goaf, methane movement and accumulation in and around the goaf are revealed, technologies to retain goaf edge roadways with innovative fill technologies are developed, and technological innovations in methane extraction are made with the retained goaf edge roadways and "Y" type ventilation systems.

The research and application of large power roadheader

Zhang Lansheng,Wei Jingsheng,Yang Yang,Song Yuehui

Strategic Study of CAE 2011, Volume 13, Issue 11, Pages 50-58

Abstract:

Developing rock roadway of coal mine is a hard task at present.Mechanized drivage of rock roadway has become a common technical problem of every coal mine.,Ltd. has researched and developed a rock roadway roadheader that has proprietary intellectual propertyrights and advanced technology, and can meet rock roadway drivage demand in China.We have achieved breakthrough in many aspects, such as heavy rocky roadway roadhead in the overall design
