Abstract
The invention discloses a temporary supporting method for a tunneled roadway. The problems that a coal seam roof is broken and the working efficiency is low due to the fact that the operation is conducted when the coal seam roof is not supported, and supporting is conducted repeatedly during existing tunneled roadway operating are solved. The temporary supporting method comprises the steps that temporary supporting of an exposed coal seam roof newly tunneled by a tunnel boring machine is conducted when a tunneled roadway retractable temporary bracket and the tunnel boring machine work cooperatively; and roadway permanent supporting operation is conducted with the assistance of the tunneled roadway retractable temporary bracket. According to the temporary supporting method for the tunneled roadway, the design is reasonable, the process is mature and reliable, and supporting equipment is stable and safe; traditional tunneling and anchor supporting staggered operating modes are replaced with continuous tunneling and continuous anchor supporting operating modes, the wasted preparation time for alternation of the tunneling process and the anchor supporting process is shortened, and the tunneling efficiency and the anchor supporting efficiency are remarkably improved; and thus, the newly-exposed coal seam roof of a tunneled working surface is temporarily supported, and the safety of the tunneled working surface is improved.
Description
Technical field
The present invention relates to a kind of digging laneway temporary support method.The gib of pick exposure top board new to development machine when a kind of digging laneway telescopic type falsework and development machine coordinating operation, the method utilizing digging laneway telescopic type falsework adit permanent support operation, it is mainly used in down-hole driving face, the top board that development machine excavation operation has just been exposed and the temporal mechanical supporting of lateral wall, auxiliary permanent supporting operation, provides effective safety guarantee for operating personnel.Belong to lane digging laneway support process technical field.
Background technology
In the pit mining of current mining, especially colliery, the excavation operation of underworkings is the prerequisite of every other mining operations.China's fully mechanized workface does not the most use temporary support facility; the present situation of major part down-hole piercing technique is shut down after being generally tunneling machine cutting one cutter coal; development machine is withdrawn from; workman takes the material equipment such as anchor net, anchor pole, anchor cable and jumbolter and enters front end, carries out lapping, plays the permanent support operation such as anchor pole, anchor cable.The development machine working time only needs 5-10 minute among these, and the permanent support activity duration is even more long-time up to 20-30 minute, and the Homes Using TV of development machine only has about 25%, and this just becomes restriction development machine production efficiency and the main cause of development end fltting speed." safety regulations in coal mine " specifies, " development end forbids sky to be set for industry ", temporary supporting device of driving working face is mandatory equipment, traditional temporary support device can not support empty top in time, top board can not be effectively prevented from repeatedly support, cannot fundamentally solve laneway temporary support problem, it is impossible to provide help for permanent support operation.
This poses and improve drivage efficiency and ensure this two large problems of safety of driving face.Pick exposure top board new to development machine carries out gib with during development machine coordinating operation to make full use of above-mentioned " digging laneway telescopic type falsework ", the top board the most just exposed can be carried out supporting, development machine operation and gib are carried out simultaneously, development machine can tunnel continuously, reaches to promote the purpose of drivage efficiency；The method utilizing digging laneway telescopic type falsework adit permanent support operation, driving, Anchor Care process is made to be carried out continuously, decrease tradition driving, the time of Anchor Care alternately operating, accelerate Anchor Care efficiency, while realizing mechanization gib, significant for improving drivage efficiency.
Summary of the invention
1. a digging laneway temporary support method, the gib of top board is exposed including pick new to development machine with development machine coordinating operation, utilize digging laneway telescopic type falsework adit permanent support operation, it is characterised in that: the concrete operation step of digging laneway temporary support is as follows:
Step one: one group of digging laneway telescopic type falsework is arranged sequentially in the tunnel completing permanent support by tunnelling end；Development machine is in the front end of whole support group, and support group, across on development machine, is launched to support back and lateral wall, provided supporting for driving face；
Step 2: operation support hydraulic system is by the stent collapses of support group rearmost end, it is delivered to support group front end by the monorail crane below support, anchor net, steel band are placed on the back timber shrinking support, meanwhile development machine normally tunnels, forward after one step pitch of cut, the support of contraction is moved to the new top board exposed by monorail crane immediately, the support of contraction is launched to be supported on top board and the lateral wall of new exposure by operation support hydraulic system, and anchor net, steel band are also scheduled at back with set cap；
Step 3: development machine continues to work continuously, repeats step 2 until whole support group all moves to the top board of new pick, completes continuous excavation operation；Development machine is moveed backward, and withdraws from below support group completely, uses roof-bolter etc. to pierce in back by anchor pole, anchor cable by the armature boring that support is reserved, completes permanent support operation；
Step 4: repeat to appeal step and complete the headwork in whole piece tunnel.
Digging laneway temporary support method the most according to claim 1, it is characterized in that: described digging laneway telescopic type falsework is made up of multisection type back timber, face guard, all kinds of hydraulic jack, across above development machine during expansion supporting, back timber, hydraulic cylinder are collapsible, can be transported by the monorail crane of lower section in the middle part of set cap.
Digging laneway temporary support method the most according to claim 1, it is characterised in that: the length of single support is identical with development machine step pitch, and the particular number of support group is determined by length during heading driver；
The present invention has the advantage that and good effect is: use digging laneway telescopic type falsework, development machine is coordinated to carry out cut operation, the new top board exposed can be carried out supporting in time, do not affect working continuously of development machine simultaneously, accelerate drivage efficiency, digging laneway telescopic type falsework adit is utilized to carry out permanent support operation, Anchor Care process is made to be carried out continuously, decrease tradition driving, the time of Anchor Care alternately operating, accelerate Anchor Care efficiency, while realizing mechanization gib, significant for improving drivage efficiency.
The present invention is compared with current laneway temporary support, it is achieved that development machine work separates with permanent support operation, has liberated the constraint that pick, anchor are alternately brought to drivage efficiency largely.The composite can be widely applied in the large section tunnel advance work of colliery, to ensureing that colliery is highly efficient and productive and safety in production is significant.
