The Invention relates to semi mechanized hydraulic supported roof fortification used for supporting the roof in order to perform safe production of underground mines.
The fortifications to be used for extraction of underground mines are of high importance in terms of safety and production quality and quantity. For this purpose, various studies have been conducted, yet, the most widely used ones are tree fortification and iron pole steel wrapping fortifications.
These fortifications are not pushed towards the mirror together with coal for example, during coal mine production, which can be extracted in standing position instead, when there are improvements in the mirror, tree or iron pole steel winding fortification erected with re-workmanship is erected again in a manner that requires fairly long time and work force. Re-workmanship and time loss caused by this increase the cost and these fortifications are insufficient for forming much more sheltered area in terms of safety of the workers.
Given a point where underground work is performed, pressure on these fortifications and increase of this pressure are directly proportional to acceleration due to gravity, intensity increase and density increase. As this is clear from here, pressure share corresponding to the fortifications covering roof pressure in the legs together with depth increase. This case pose disadvantage for reducing underground site safety when depth increases. Occupational safety has become so significant that tree fortifications and iron pole steel winding fortifications are not safe enough. At the same time, tree fortifications are extremely unsafe in terms of fire. Besides creating much safer working environment with extra power provided by semi mechanized hydraulic supported roof fortification developed for eliminating these issues, installation and progress of the fortification with the movement provided in hydraulic power becomes extremely easy. This, alongside security, makes an important contribution for increasing economic gains and efficiency due to increase of fortification installation rate and reduction of work force.

Each hydraulic fluid hoses described in the specification and used in semi mechanized fortification are resistant to hydraulic pressure. AH of the pistons in the system can be stimulated with the pressure provided by hydraulic fluid from these hoses.
Semi mechanized fortification subject to the invention comprises the modules with the same feature of one another. Allowing lateral joining of the desired number of modules to interview shield body bearing girder (15) and shield body group joint plates (16) and fix shield body group joining pins, the semi mechanized fortification, the semi mechanized fortification subject to the invention ensures that the hydraulic fluids from high hydraulic pressure resistant fluid hoses and regulating the movements of these modules are directed to the pistons and provides the desired movement for the occurred pressure to stimulate the pistons.
Each module also comprises (1) four leg pistons and serving as leg function, hydraulic pressure resistant hose fluid hoses (2) to the leg pistons stimulating these pistons (1); front slider (5), two front slider pistons (3) stimulating front slider (5), hydraulic pressure resistant hydraulic fluid hoses (4) to front slider pistons stimulating front slider pistons (3); rear cape (8), one rear cape piston (6) moving the rear cape (8); hydraulic pressure resistant fluid hoses (7) to the rear cape piston, transmitting hydraulic fluid moving the rear cape pistons (6), shield body group (14), one shield progress piston (9) moving the shield body group (14), hydraulic pressure resistant fluid hoses (10) to shield progress piston moving shield progress piston(9); control unit (11) controlling the hydraulic fluid controlling propulsion, thus, movement of hydraulic fluid; position valve (12) ensuring equal transmission to the front slider pistons (3) via hydraulic pressure resistant fluid hoses (13) between the position valve and control unit moving the front slider pistons of the high pressure from the control unit (11) at the same time controlling the hydraulic fluid; hydraulic pressure resistant fluid hose (13) between the position valve and control unit moving the front slider pistons at the same time; shield body group (14), two shield body bearing girders (15), four shield body group joining plate (16) in a manner that bearing girder shall be at the right and left ends and pins for joining shield body group (17).
The semi mechanized fortification subject to the invention used for fortifying the roof by being fed with hydraulic power for performing safe production in the area to be fortified (1) is positioned on shield body group (14). The units are ensured to be moved by upward and downward movement and being driven with hydraulic fluid via hydraulic pressure resistant fluid hoses (2) to leg pistons of leg pistons on shield body group (1). (Figure-10) it is ensured that the module is in suspended condition in the air in a manner that the unit is fixed to a single module by being lifted upward via the control unit (11) controlling the hydraulic fluid driving the hydraulic fluid (1) of the leg pistons. (Figure-18). High pressure fluid to the control unit (11) controlling the hydraulic fluid is delivered to the hydraulic pistons via hydraulic pressure resistant hoses. (Figure-10). High pressure hydraulic fluid is transmitted for moving the hydraulic pistons with the control unit (11) controlling the hydraulic fluid.
In this way, it applies piston opening or closing movements. The position valve (12) ensures that the pressure from the control unit (11) controlling the hydraulic fluid is equally transmitted to the front slider pistons (3) via hydraulic pressure resistant fluid hoses (13) between the control unit and position valve moving the front slider pistons and the pressure from the control unit (11) at the same time controlling the hydraulic fluid. In this way, it completes the movements in equal time and equal distance without compressing the front slider pistons (3) construction. There are two parts in the modules as the front slider pistons (3) (Figure-9) the front slider pistons on the unit ensures that the front slider (5) is moved in forward and backward position by being driven with the hydraulic fluid via the hydraulic pressure resistant fluid hoses (4) to the front slider pistons. (Figure-9). Single modules on the lateral side with the shield body group joining (16) ensures the fortification of the area by pushing the shield progress piston (9) in forward and backward position through the shield body bearing girder (15) and the pin for joining shield body group (17). (Figure-11) Movement of these parts is ensured by being driven with the hydraulic fluid transmitted via the hydraulic pressure resistant liquid hoses (10) to the shield progress piston of the shield progress piston (9) to shield progress piston. In this way, these units transmit one another to the area where productions are performed. The rear cape piston ensures that the rear cape is opened and dosed (8) by being driven with the hydraulic fluid via the hydraulic pressure resistant fluid hoses (7) to the rear cape piston with the driving pressure from the control unit (11) controlling the hydraulic fluid. (Figure-8). In this way, it is ensured that coal is safely flowed. At the same time, the rear cape (8) ensures the shield progress and that the coal from the rear area is retained and stone and coal are segregated in a controlled manner.
