摘要
针对矿山井下液压提升机硐室中受限空间噪声环境,应用噪声统计分析仪、声强分析系统等测试仪器对液压提升机硐室噪声进行了现场测试并进行了声压级统计分析和声强云图分析,结果表明硐室空间各处声压级均大于85dB;探讨了矿井硐室噪声控制主要途径,对影响液压提升机硐室受限空间噪声控制的主要影响因素如吸声系数α、硐室内表面积S和硐室容积V进行了分析,提出了适当增加硐室内表面积S和增大吸声系数α的提升机硐室噪声控制措施.
Aiming at the confined space noise environment of hydraulic hoist cavern, this paper measured sound field parameters with the noise statistical analyzer and sound intensity analysis system, and analyzed the sound pressure and sound intensity distribution. Results showed that the sound pressure were larger than 85 dB everywhere in the cavern space. Main ways to control the mine cavern noise were discussed, the main influence factors such as a and S and V that affect the hydraulic hoist cavern limited space noise control were analyzed, and the noise control measures were put forward.
