智能恒减速电液制动是当前世界大型矿山提升设备认可的安全控制技术，逐渐成为大型矿井提升系统的重要配套系统。目前，我国井工煤矿生产过程，主要依靠矿井提升机进行生产作业，因此矿井提升与制动的安全可靠性对矿井的安全生产起着至关重要的作用。矿井提升机提升运输任务，涉及财产及人身安全。因此，我们在关注矿井提升速度与效率的同时，更要重视矿井提升系统的安全制动性能。 制动系统是保障矿井安全提升的咽喉设备环节。目前国内矿井提升设备大多数采用的是恒力矩制动控制，但是这种制动控制方式在可靠性方面存在一定的隐患和不足。在提升机出现故障时，制动过程不平稳，极大降低了设备的安全性能和使用寿命。科技的发展，制动技术不断的更新，使矿井引进恒减速电液制动控制系统，虽然提高了提升系统的安全性，但其耗费过多。因此，本文所研究的矿井提升智能恒减速电液制动系统，克服上面缺点，提高煤炭安全生产。 本文以神华宁煤集团石槽村矿副井提升机恒减速制动系统为例，针对提升制动安全存在的问题采用智能恒减速电液制动方式，从恒减速制动控制原理入手，探讨了其基于网络化PLC控制方案和基于智能控制的模糊控制策略。文中从其系统组成、控制策略和现场运行情况研究分析，其采用性能稳定的恒减速制动，并备用两路二级制动回路，并且采用安全可靠的配套电控系统，使系统具有高程度智能化、好的安全制动性、全方位安全保护和故障监控措施等特点，其大大提高矿井提升机安全运行水平，在矿井提升机恒减速电液制动系统领域满足了提升设备对于矿井提升智能恒减速电液制动系统的需求，并为企业和社会创造社会效益和经济效益，具有深远的意义。

Intelligent constant deceleration electro-hydraulic braking is a safety control technology recognized by large mine lifting equipment in the world and has gradually become an important supporting system of large mine lifting system. At present, the production process of coal mine depends mainly on mine hoist, so the safety reliability of mine hoist and brake plays a vital role in the safety production of mine. Mine hoist lifting transport task, involving property and personal safety. Therefore, we should pay more attention to the safety braking performance of mine hoisting system while paying attention to the speed and efficiency of mine hoisting. The brake system is the throat equipment link which guarantees the safety. At present, most of domestic mine hoisting equipment adopts constant torque braking control, but this braking control method has some hidden dangers and deficiencies in reliability. When the hoist fails, the braking process is not stable, which greatly reduces the safety performance and service life of the equipment. With the development of science and technology and the update of braking technology, the constant deceleration electro-hydraulic braking control system is introduced into the mine. Although the safety of the hoisting system is improved, it costs too much. Therefore, the intelligent constant deceleration electro-hydraulic braking system of mine hoist studied in this paper can overcome the above disadvantages and improve the safety and productivity of coal. Taking the constant deceleration braking system of auxiliary shaft hoist in shicaocun mine of shenhualing coal group as an example, this paper adopts the intelligent constant deceleration electro-hydraulic braking mode to solve the problems existing in the safety of hoisting braking. Starting from the control principle of constant deceleration braking, this paper discusses the networked PLC control scheme and the fuzzy control strategy based on intelligent control. In this paper, from the system composition, control strategy and field operation research and analysis, it USES the constant deceleration braking performance is stable, and secondary braking circuit spare two road, and the safe and reliable electric control system of form a complete set, make the system with a high degree of intelligence, good safety brake, comprehensive security protection and fault monitoring, etc, it greatly improve the level of safe operation of the mine hoist, the mine hoist constant deceleration electric hydraulic brake systems meet the lifting devices for mine hoists intelligent constant decelerate the demand of the electric hydraulic brake system, and create economic benefits and social benefits for the enterprise and the society, has the profound significance.
