Uranium mining in the seepage of radon and its daughters and Control
Precipitation of radon seepage control. It can be used to make the avalanche formed between the body and recovery with a negative pressure (or vacuum groove) of the pressure distribution adjustment method to cut off the body of caving to the mining area of high concentration of radon seepage,
Beats By Dre Headphones, and directly into the return air Road, also according to mining conditions, the use of avalanche probe around the lower body Lane,
Oakley sunglasses sale, the old roadway, install high-pressure ventilation fan for mandatory direct surface. Partial control. Mainly refers to an open fracture of the rock, filling the body,
herve leger skirts, leaving the ore pile, between the two Lane radon seepage control methods; visible on the circumstances, were used to boost, buck or balance the air pressure method; or create special row of radon systems to control radon seepage precipitation or precipitation of the direction of turning its back to the work area. 4 Conclusion mine radon control, you must first identify the source of radon, radon exhalation of the nature and characteristics, full ventilation of the two fundamental roles, pay attention to rationalizing the distribution system network in the wind pressure on the mine seepage of radon control of precipitation reduce the precipitation of radon in mines and improve the utilization of force and the dilution air flow, lower radon is to improve ventilation, to ensure that underground mining sites and the surface environment from pollution, improve ventilation and technical and economic rationality an important way.

(Received Date: 2004-02-18) (author] Liu (1971 a) Male Master instructor who Chaoyang of Liaoning current international trends in mining equipment, mining industry is the backbone of global economic development, the developed countries in recent years the rapid development of mining equipment, new products The new technologies are emerging. The following is today's trend of foreign mining equipment. open pit mining equipment with a large-scale open pit mining of foreign advanced open pit mining equipment are the two biggest features: First, large-scale mining equipment,
mulberry bags uk, the second is equipped with Intelligent Automation 1995 Komatsu 272-ton 930E launched mine car, in 1998 the company introduced the CAT797 Caterpillar Model 327 t mining truck order with large mining truck matching, P & H4100-type power bucket capacity reached 35 cubic meters, four 327-ton shovels can be filled with a mine car. 59R, 61R rotary drill drill hole reached 445 mm, axial pressure of 184 tons and 152 tons, torque of 20,000 Newton * Newton meters and 30,000 meters into the 20th century, 90 years, foreign large-scale open pit equipment,
true religion outlet, single-board computer real-time monitoring has been applied successfully in recent years, the U.S. module Mining Systems, Inc., Caterpillar Inc. by means of global Positioning System (GPS) and high-performance data communications network technology, has developed the computer software, to automate a variety of intelligent control and management equipment. underground mining equipment trends: First, complete set equipment, high degree of mechanization. advanced underground mining equipment to the shipping charge from the rock, underground facilities all mechanized operations, the manual procedure without manual operation, no heavy physical labor. all types of hydraulic drills, hydraulic rock drill, diesel or electric and remote Scraper machine is very common basic equipment. equipment, large-scale, micro, serialization, standardization, universal high degree of these complete set mechanical characteristics. The second is equipped with trolley-based, hydraulic-based, high degree of automation. Third, equipment and technology will be able to mature, and has successfully introduced the unmanned, robotic operations and other new technologies. high reliability. foreign mining companies tend to use the world's leading professional manufacturer of mining equipment products, such as the use of world-renowned mining equipment manufacturer Atlas, Wagner company, GHH companies, Yi Muke products of these world-renowned manufacturers of products proven technical performance, high reliability, technology and good service. uranium mining in the flow of chlorine and its daughters and Control 65
