Full preparation before equipment operation is an important link to ensure good performance, safety and reliability of mechanical equipment after delivery. The overall inspection includes no-load test run, load test run, inspection after test run, etc. Pressure test and compactness test are also needed for important equipment. For mining loaders and other machinery with complex working environment, the preparation work is particularly important to ensure that the machinery can play a higher role in the follow-up construction and ensure the smooth operation process.

矿用装载机作业前准备工作的主要内容包括：

The main contents of preparation before operation of mine loader include:

1、应该检查电源系统：电缆、接头应改确保完好，无破损的现象；连接线路应完好，无烧损、松脱现象。

1. First of all, the power supply system should be checked: the cables and joints should be changed to ensure that they are in good condition without damage; The connecting line shall be in good condition without burning and loosening.

2、检查装载机的液压系统：液压系统的元件及其联接管路之间连接应紧固，无明显渗漏现象；液压油位应符合规定（油量约占油箱总容积的4/5之间）。

2. Check the hydraulic system of the loader: the connection between the components of the hydraulic system and its connecting pipes should be tight without obvious leakage; The hydraulic oil level should meet the requirements (the oil volume accounts for about 4 / 5 of the total volume of the oil tank).

3、检查矿用装载机的操纵系统：各操纵手柄应处于中立位置，操纵应灵活，无卡滞现象。

3. Check the operating system of mine loader: all operating handles should be in the neutral position, and the operation should be flexible without jamming.

4、检查输送系统：输送带应完好，张紧度合适；滚轮、滚筒转动灵活，无异常音响。

4. Check the conveyor system: the conveyor belt should be in good condition with proper tension; The roller and roller can rotate flexibly without abnormal sound.

5、发动机运转时，每个气缸每分钟吸入空气2～4m3。为了保证进入气缸的空气干净，使用前须对空气滤清器加强检查，定期清洗。

5. When the engine is running, each cylinder inhales 2 ~ 4m3 air per minute. In order to ensure that the air entering the cylinder is clean, the air filter must be inspected and cleaned regularly before use.

6、安装空气净化滤清装置：矿山井下开采空间狭小、通风条件差,矿井铲车作业时产生的尾气难以及时、顺畅排放到矿井之外,由此造成井下空间污染严重,给工作人员的健康带来危害。矿井铲车本文主要讲述矿井铲车柴油机尾气的危害,提出净化方法,并介绍水洗式尾气过滤装置。

6. Installation of air purification and filtration device: the mining space is narrow and the ventilation condition is poor, so the tail gas produced by forklift operation is difficult to be discharged out of the mine timely and smoothly, which causes serious pollution of underground space and brings harm to the health of workers. Mine forklift this paper mainly describes the harm of mine forklift diesel engine exhaust, puts forward the purification method, and introduces the water washing exhaust gas filtering device.
