由于煤炭生产的特殊性，因此要求煤矿矿用产品必须具有可靠的安全性能。煤矿井下用的各种产品，除都具有生产工具的属性外，还要满足适应井下恶劣环境条件的特殊要求。因此，基本上是为煤矿专用设计的产品，能在其它使用场合通用的设备极少。

Due to the particularity of coal production, it is necessary to have reliable safety performance. In addition to the properties of the production tools, all kinds of products used in underground coal mines must meet the special requirements for the conditions of poor conditions. As a result, it is basically a product designed for coal mines that can be used very rarely in other USES. 

　　煤矿用阻燃输送带在运行中，不得产生静电火花，在事故性摩擦情况下不得摩擦着火。即使矿井发生大型火灾，其燃烧速度不得高于井下其它可燃物，且一旦远离火源便自行熄灭。

The fire retardant conveyor belt of coal mine is in operation, no electrostatic spark can be produced, and no friction can be caused by accident. Even if a large fire occurs in a mine, it may not burn more than any other combustible in the mine, and if it is kept away from the fire, it will go out. 

　　煤矿用阻燃电缆，不仅要求其具有阻燃、抗静电性能，还要求其在电缆护套内加设半导体屏蔽层，纵然受到事故性撞、砸、挤、压时，只准超前断电，绝不允许相间和相地短路。

Flame retardant cable, not only requires its flame retardant, antistatic performance, also requires the added a semiconductor shield inside the cable sheath, even if by accident hit, hit, squeeze, pressure, power only allowed in advance, and will never allow and phase short circuit. 

　　国家必须采取强制性的安全管理手段、措施确保煤矿矿用产品满足煤矿安全生产的特殊需要。煤矿矿用产品执行安全标志管理制度，就是要求煤矿矿用产品在技 术上满足煤矿安全标准要求，煤矿矿用产品由具备生产条件的生产单位生产，煤矿矿用产品在安全性能和使用性能上满足煤矿安全生产要求。

The state must adopt mandatory safety management measures and measures to ensure that coal mine products meet the special needs of coal mine safety production. Coal mine product safety sign and managing the system, that is, coal mine explosion-proof products meet the requirements of coal mine safety standards on technology, coal mine production by the production conditions of unit production, coal mine explosion-proof products on the safety performance and the use of performance to meet the requirements of coal mine safety production.
