Qhov no tsis yog tsuas yog nce tus nqi txij nkawm tab sis tseem cuam tshuam rau qhov chaw tsim khoom thiab kev thauj mus los zoo vim cov khoom xau. Baohua's hnav-cov hlau tsis muaj zog rau mining chutes, nrog nws cov ultra- siab hnav tsis kam, txo qhov hnav ntawm cov ntaub ntawv nyob rau sab hauv phab ntsa ntawm chute, ncua kev pab cuam lub neej ntawm chute.Ib txhij, lawv cov kev cuam tshuam zoo heev tuaj yeem tiv taus qhov cuam tshuam ntawm cov ore loj, tiv thaiv kev tawg. Siv Baohua's hnav-cov hlau tsis muaj zog rau cov mining chutes tuaj yeem txo qhov zaus thiab tus nqi ntawm kev saib xyuas rau cov lag luam mining, xyuas kom cov khoom siv thauj mus los zoo, zam cov khoom xau, txhim kho qhov chaw tsim khoom, thiab txhim kho kev thauj mus los ntawm mining.
