1.3 equipment rental fee control system
1.3. 1 Calculation method of single equipment rental unit price
The rental unit price of equipment is calculated according to a certain proportion and requirements on the basis of the original value of equipment, and the equipment rental fee is obtained by the sum of depreciation fee, management fee and repair fee.
Depreciation expense (month) = original value of equipment ×97%÷ depreciation period ÷ 12.
Repair cost (month) = original equipment value ×5%÷ 12.
Management fee (month) = original value of equipment × 1% calculation.
Monthly rental fee for single equipment = depreciation fee+repair fee+management fee.
1.3. 1. 1 daily mobile device calculation method
The original value of daily mobile equipment is small, and the mobility is relatively large, so it is easy to cause waste when used underground. If the rental fee is calculated according to the original value of the equipment, the amount is relatively small and the user will be indifferent. Therefore, in order to strengthen the assessment of this part of equipment, the rental fee of this equipment will be charged at 5 times of the original calculation.
1.3. 1.2 Calculation method of single common equipment
Ordinary equipment is less mobile, the use of equipment is relatively stable, and the assessment strength does not need to be too great. Charge according to the equipment charging formula. 、
1.3. 1.3 Calculation method of single large fixed equipment
Large-scale fixed equipment is mostly equipment that no longer flows after installation, mainly fully mechanized mining equipment used in coal mining face and fixed conveying equipment used in transportation roadway. If the rental fee is high, it will be assessed at 20% on the basis of the calculation of equipment rental charge in the assessment process.
1.3.2 equipment classification and rental fee evaluation
Classify standard equipment, such as coal mining, tunneling, drilling, etc. , and defined the assessment methods of all kinds of equipment rental fees, which are divided into quota assessment and quota assessment. Equipment closely related to output and footage should be in the form of fixed unit price.
The implementation of the quota is linked to the operation efficiency of the equipment, and the standard configuration of the equipment needed for the construction technology of each district team is formulated, so as to calculate the quota of tons of coal and the quota price of linear meters of each district team. Other equipment adopts the quota unit price method, and the quota is evaluated by the extended lease period of equipment, mainly including drainage equipment and transportation equipment.
1.3.3 equipment standard configuration
1.3.3. 1 Standard configuration method of equipment

(1) working face mining
Due to the complexity of coalfield geological conditions, coal mine equipment is multi-level. At present, fully mechanized mining, conventional mining and blasting coexist.
① Fully mechanized mining face
The standard configuration of fully mechanized mining face equipment is mainly composed of shearer, conveyor, support and related control and auxiliary equipment.
There are 1 shearer in the working face, which should meet the needs of coal seam mining thickness and coal cutting resistance, adapt to coal seam dip angle, support and conveyor, and have good spraying and dust suppression devices;
Scraper conveyor 1 set, transfer conveyor 1 set, meet the length and inclination of the working face, and can be matched with shearer. At the same time, according to the actual situation of coal mining and the size of coal block, choose whether to configure a set of corresponding crushing equipment to make the shearer work and match with the support to ensure the normal work of the shearer.
The support should be supported, and its initial supporting force and working resistance should adapt to the pressure generated by the movement of the direct roof and the old roof and floor, so as to limit the roof subsidence to a minimum. If you want to move, the support should have the function of moving by itself according to the progress of coal mining work.
In order to meet the needs of ventilation and pedestrians and match the shearer conveyor, the number of supports should be calculated according to the length of the working face and the width of the supports.
Secondly, according to the equipment model, current and other related technical parameters, the corresponding number of power supply equipment is configured to ensure the normal operation of the equipment.
