For the Optimization Solution problem of multiple objective function, the method for Ying Liyong static configuration is calculated, due to above-mentioned more
Objective function Relationship Comparison is complicated, and F1And F2It is not XiContinuous function, calculate optimal solution X with conventional Method of Seeking DerivativeiIt is
Unworkable, it can calculate by the following method, initial X should be set according to total construction work amount firstiValue, according to more
Objective optimization configuration function calculates corresponding F1And F2；Then least square is pressed to these initial numerical value using MATLAB software
Principle carries out fitting of a polynomial, draws F1And F2About XiHigher order functionality curve graph；Finally according to F1And F2Higher order functionality it is bent
Line chart carries out coordinating to correct obtaining corresponding Z using set of weights is legal to two objective functions1And Z2, to obtain one to each point
Opposite optimal solution of all preferable scheme of target as multiple objective function.
Step 2: each equipment conveying in construction system in place and is debugged, and to be repaired section of tunnel is cleared up, by striking
Side jowling checks back and two stability helped, uses anchor cable (bar) reinforcement to unstable surrounding rock.
Operator carries equipment according to suitable two operating of site operation environment and condition selection, by operating roadway repair
The quartering hammer 11 of machine is crushed pucking tunnel, the fortune scratch board conveyor that spoil is passed through laneway repair machine using bucket 13
Structure 15 is transferred to two operatings and carries in equipment, and two operatings carry equipment and are transported through spoil, and by laneway repair machine 1 to tunnel bottom
Plate is compacted.
Step 3: pre-pouring grout construction for reinforced roadway floor crack and blocks tunnel bottom due to roadway floor soft broken
Plate surface layer country rock prevents roadway floor anchor rope grouting hole collapse hole.Operator carries out the construction of pre-pouring grout hole using anchoring drilling machine 3,
Pre-pouring grout pipe and sealing of hole are installed, grouting slurries are prepared using mixing plant 5, completes slip casting operation using grouting pump 4, and carry out marquis
It is solidifying.
Step 4: anchoring construction, operator are carried out the construction of anchor hole using anchoring drilling machine 3, are used cooperatively after pore-forming
Resin anchoring agent installs high strength steel strand anchor cable, configures the high-intensitive arch tray of abnormity, installs aligning ball pad additional, and in drilling
It is inserted into slip casting aluminium-plastic pipe, using cotton yarn and double slurries sealing of holes, by slip casting aluminium-plastic pipe to anchor cable hole slip casting, after the completion of slip casting, and
Carry out Hou Ning.
Step 5: anchorage cable stretching and smooth location, operator pre-tightens anchor cable using 7 tensioning of tensioner, after the completion of tensioning,
Artificial separation anchor cable head tendon, bends, around to prevent lockset from loosening.
Entire construction system can carry out continuous high-efficient repairing construction operation, after the completion of construction, need to entire construction
Place clear up perfect, and each equipment is transported and IMM algorithm.
The construction system and its construction method that baseboard of coal mine roadway of the invention is quickly repaired as a result, can be according to tunnel bottom
The requirement of plate repairing construction technique reasonably selects relative special-purpose equipment and arranges the position of each equipment, by Optimal Configuration Method and
Scheduling decision method, determine respectively each equipment quantity and real-time matching relationship.The construction system uses procedure operation, construction
Each equipment can realize automatically walk in system, and mechanization degree is high, and labor intensity is small, can greatly improve baseboard of coal mine roadway
Repairing construction speed improves operating environment, reduces construction cost.
