Abstract
The invention discloses a kind of roadway workface supporting construction, it is characterised in that：Including stalk arch steel canopy, wire netting and plank lagging, the uniform plank lagging on stalk arch steel canopy, steel wire is set on stalk arch steel canopy arch top.The present invention carries out supporting when roof wraps up in rubble in yellow mud to its roadway workface, and technology is reasonable, safe and efficient, and it can solve the problem that in alley way anchor host's Bracing Process, the problem of top plate drilling crevice water water yield is larger, and Anchor Agent Loss is serious, supporting effect is good；It can be widely used for coal road breaking roof, mining roadway and gib etc..
Description
Technical field
The invention belongs to the technology category of well work mine laneway surrounding rock stability, and in particular to one kind is wrapped up in for coal seam yellow mud
The roadway workface supporting construction of rubble top plate.
Background technology
It is mainly K2 limestone that, which there are some coalfields such as Qinshui coalfield 15# roofs in Shanxi, and thickness is 6 ~ 11m, is locally had
False roof, directly top and base object model are K2 limestone, belong to Taiyuan group.When lid mountain thickness is less than 100m, Taiyuan Forma-tion
Stratum is degraded, especially Lower and middle mountain areas, and Tu Liang and coombe development, cutting are deeper；K2 limestone is weak watery water-bearing layer,
Top loose overburden pores'growth is caused, superficial part bedrock weathering zone rock fracture is developed, rock crushing, can in lower floor's limestone
See small dissolution pore or corrosion fissure.By the affiliated Mount Huang of Shanxi coal transportation and sales group, the palm Shi Gou with and contain three mines exemplified by, K2 lime
Rock top plate Karst Fissures are developed very much, and top plate is granular limestone, and the charges of Karst Fissures are yellow mud, overall to wrap up in rubble in yellow mud
Shape, in mining roadway anchor host moves Bracing Process, top plate drilling crevice water water yield is larger, and Anchor Agent Loss is serious,
The serious selection for restricting roadway workface support pattern, and then influence supporting effect of roadway；On the other hand, roadway workface has it
Own characteristic, predominantly service time are shorter, mostly 5 ~ 11 months, and drift support type need not be excessively complicated.For coal seam
Yellow mud wraps up in the own characteristic of this geological conditions of rubble top plate and roadway workface, invent a kind of technology it is reasonable, it is safe and efficient,
The good roadway workface supporting construction of supporting effect seems very necessary.
The content of the invention
The object of the invention aims to solve the problem that coal seam yellow mud wraps up in the roadway workface support issues of rubble top plate, there is provided a kind of technology
Rationally, the roadway workface supporting construction safe and efficient, supporting effect is good.
To reach above-mentioned purpose, the present invention uses following solution：A kind of roadway workface supporting construction, its feature exist
In：Including stalk arch steel canopy, wire netting and plank lagging, the uniform plank lagging on stalk arch steel canopy, in stalk arch steel canopy
Arch top sets steel wire.
The present invention is to propose a kind of roadway workface supporting construction, pin on the basis of the research of existing improving stability of surrounding rocks in roadway
To the self-characteristic of coal seam K2 limestone roofs, effectively solve working face of coal seam roadway support issues.In roadway workface with adopting
The crosspoint in area tunnel and connection roadway section, using stalk arched roof formula support pattern, by stalk arch steel canopy, wire netting and wood
Backboard forms；In roadway workface section, when K2 limestone roofs are complete, using bolting with wire mesh mode, by anchor pole and bar-mat reinforcement
Composition；When K2 limestone roofs wrap up in rubble in yellow mud, using stalk arched roof formula support pattern, by stalk arch steel canopy, iron wire
Net and plank lagging composition.
Compared with prior art, the present invention has substantive distinguishing features following prominent and significant effect：
1st, the present invention includes stalk arch steel canopy, wire netting and plank lagging, when roof wraps up in rubble in yellow mud to its work
Face tunnel carries out supporting, and technology is reasonable, safe and efficient, and can solve the problem that in alley way anchor host's Bracing Process, and top plate drilling splits
The problem of gap swelling water is larger, and Anchor Agent Loss is serious, supporting effect is good.
2nd, coal road breaking roof, mining roadway and gib etc. be the composite can be widely applied to.
Brief description of the drawings
Fig. 1, the present invention structural representation.
Fig. 2, bolting with wire mesh structural representation.
In figure：1st, stalk arch steel canopy 2, wire netting 3, plank lagging 4, anchor pole 5, bar-mat reinforcement.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Embodiment 1：
The working face air intake crossheading of certain ore deposit 15# coal seams 15101, clear span 4.6m, clear height 5.0m, average lid mountain thickness 88m, air intake crossheading
Being communicated with an exploiting field adhesive tape lane, air return way communicates with an exploiting field return airway, using sectional, based on bolting with wire mesh, stalk arch
Supplemented by shape shed ding support, crossheading and mining roadway crosspoint section, using stalk arched roof formula supporting construction, support material is by straight
Wall arch steel canopy 1, wire netting 2 and plank lagging 3 form；In air intake crossheading section, when K2 limestone roofs are complete, using anchor net branch
Shield mode, support material are made up of anchor pole 4 and bar-mat reinforcement 5；When K2 limestone roofs wrap up in rubble in yellow mud, using stalk arched roof
Formula support pattern, support material are made up of stalk arch steel canopy 1, wire netting 2 and plank lagging 3.
It is good to test supporting effect, solves the roadway workface branch that 15101 working face air intake crossheading mud wrap up in rubble top plate
Shield problem.
Embodiment 2：
The working face haulage gate of certain ore deposit 15# coal seams 15101, clear span 5.0m, clear height 5.0m, average lid mountain thickness 20m are suitable transporting
When groove K2 limestone roofs are complete, using bolting with wire mesh mode, support material is made up of anchor pole 4 and bar-mat reinforcement 5；K2 limestone top
When plate wraps up in rubble in yellow mud, using stalk arched roof formula support pattern, support material is by stalk arch steel canopy 1, wire netting 2 and wood
Backboard 3 forms, and efficiently solves the roadway workface support issues that 15101 working face haulage gate mud wrap up in rubble top plate.
