井下装载机施工环境特点

characteristics of underground loader construction environment

井下一般指地下采矿时，为采矿提升、运输、通风、排水、动力供应等而掘进的通道。为了开采煤炭，从地面向地下开掘的各类通道和硐室都叫井下

Underground generally refers to the tunnel excavated for mining lifting, transportation, ventilation, drainage and power supply during underground mining. In order to mine coal, all kinds of passages and chambers excavated from the ground to the underground are called underground

井下装载机施工作业环境差，空间较小；地质条件多变，经常受到顶板、矿尘、水、火等灾害的威胁；生产工艺复杂，劳动强度大等

The construction environment of underground loader is poor and the space is small; Geological conditions are changeable and are often threatened by roof, mineral dust, water, fire and other disasters; Complex production process, high labor intensity, etc

1）井下坡度不大于15°；

1) The underground slope shall not be greater than 15 °;

2）井下环境温度为﹣5℃～+40℃，大相对湿度不大于90（温度为25℃时）；

2) The underground ambient temperature is - 5 ℃ ~ + 40 ℃, and the large relative humidity is no more than 90 (when the temperature is 25 ℃);

3）使用地点海拔不超过1000m，在海拔超过1000m的高原环境下使用时，应根据情况采取必要的措施或进行特殊设计；

3) The altitude of the place of use shall not exceed 1000m. When it is used in the plateau environment with an altitude of more than 1000m, necessary measures or special design shall be taken according to the situation;

4）所装载的矿岩块度大不超过400mm；

4) The loaded ore and rock block size shall not exceed 400mm;

5）电压偏差为±5。交流频率偏差为±1；

5) The voltage deviation is ± 5. AC frequency deviation is ± 1;

6）装载机工作时周围的煤尘、甲烷爆炸性气体含量应符合煤矿规程规定的含量。

6) The content of coal dust and methane explosive gas around the loader during operation shall comply with the content specified in the coal mine regulations.

【井下装载机井下施工作业常识】

[general knowledge of underground construction of underground loader]

非煤矿山有两种主要开采方式，一种是地下开采，一种是露天开采。对于埋藏较深的矿床，一般采用地下开采的方法。地下开采有其特殊的作业特点，主要是：作业环境差，空间较小；地质条件多变，经常受到顶板、矿尘、水、火等灾害的威胁；生产工艺复杂，劳动强度大等。因此，井下作业人员需要掌握一定的井下作业常识才能保证。

There are two main mining methods in non coal mines, one is underground mining and the other is open-pit mining. For deep buried deposits, underground mining is generally used. Underground mining has its special operation characteristics, mainly including: poor operation environment and small space; Geological conditions are changeable and are often threatened by roof, mineral dust, water, fire and other disasters; Complex production process, high labor intensity, etc. Therefore, underground operators need to master certain underground operation knowledge to ensure.

一、下井前的准备

1、 Preparation before running down the well

1．人井人员在人井前，一定要吃饱睡足休息好，并且人井前严禁喝酒。

1. Well personnel must have enough food, sleep and rest in front of the well, and drinking is strictly prohibited in front of the well.

2．人井前要穿戴好帽、工作服和胶鞋，做到整齐利索；脖子上好戴一条毛巾，既可擦汗，又可防矿渣掉落到衣服里去，在自救互救中也可能用上。

2. Wear hats, overalls and rubber shoes before entering the well, and keep them neat and tidy; Wear a towel around your neck, which can not only wipe sweat, but also prevent slag from falling into your clothes. It may also be used in self-help and mutual rescue.

3．人井人员需要随身携带矿灯等照明灯具。

3. The manhole personnel need to carry miner's lamp and other lighting lamps.

4．随身携带的锋利工具，如瓦刀、斧子、锯等需要套上护套或装人工具袋，以防伤人。

4. Sharp tools, such as tile knives, axes and saws, need to be sheathed or packed in tool bags to prevent injury.

5．需要遵守入井挂牌登记制度，登记后方可人井。

5. It is necessary to comply with the listing and registration system for entering the well, and people can enter the well after registration.

6．每个人井人员都需要自觉参加班前会，明确当班生产任务和注意事项，防止发生事故。

6. Each well operator shall consciously participate in the pre shift meeting, clarify the production tasks and precautions on duty, and prevent accidents.

7．接受岗前培训，取得资格证书方可人井。每个在井下工作的人员都需要熟悉自己工作地点的各种灾害情况的避灾路线。

7. Accept pre job training and obtain qualification certificate before entering the well. Each person working underground needs to be familiar with the disaster avoidance routes of various disaster situations in his workplace.

8．了解本次下井所经过路线的条件和工作环境的条件及紧急情况下的逃生路线和方法。

8. Understand the conditions of the route and working environment, as well as the escape route and method in case of emergency.
