High-depth winze shaft blocking state observation monitoring method

Abstract

The invention provides a high-depth winze shaft blocking state observation monitoring method. An observe cannon hole communicated with a high-depth winze is drilled, a flowing situation of ore in the high-depth winze when the ore is placed is observed through a voice and video frequency monitoring system after the high-depth winze is blocked, a vertical distance between a falling ore face and a central position of a cross position of the observe cannon hole and the high-depth winze, quantity of ore reserve is calculated, and the vertical distance between an ore face and the central position of the cross position of the observe cannon hole and the high-depth winze meets a setting distance requirements; a blocking position of the ore in the high-depth winze is measured; a blocking arc in a high-depth winze shaft is monitored, and stability degree of the blocking arc is judged. The high-depth winze shaft blocking state observation monitoring method provides scientific and reasonable basis for preparing a scheme to dredge the winze, and greatly improves safety work environment and labor strength of operating personnel and is accurate in ore placing control.

Description

technical field [0001] The invention belongs to the technical field of metallurgy and mines, and relates to a method for monitoring a high-depth chute, in particular to a method for observing and monitoring the blockage of a high-deep chute shaft. Background technique [0002] In the process of mining, the production mode of high-depth shaft transportation with the advantages of less investment, less equipment, low cost and large production capacity is usually adopted. However, during the production process, accidents such as blockage and landslides often occur in the high-depth chute, which seriously affect the mine production and pose a great threat to personal safety. [0003] In general, the blockage of the chute is observed through the chute, but due to the side pressure of the ore flowing in the shaft during the ore drawing process, the connection between the chute and the chute is basically blocked, and the observation needs to be cleared. However, since it is imposs...

Problems solved by technology

However, during the production process, accidents such as blockage and landslides often occur in high and deep shafts, which seriously affect mine production and pose a great threat to personal safety.

[0003] Generally, the blockage of the chute is observed through the chute, but due to the existence of side pressure when the ore flows in the shaft during the ore drawing process, the connection between the chute and the chute is basically blocked, and the observation needs to be carried out after the ballast is cleared

However, since it is impossible to judge the clogging position of the chute in advance, it is difficult to estimate when the ore surface below the clogging arch in the shaft will be drawn to the floor of the communication channel. Put the ore surface inside to the floor of the connecting road to clear the ore clogging the connecting road, and then manually observe the blockage of the chute after cleaning the ore

In the whole process of ore drawing, manual detection, cleaning of ore slag and blockage observation, operators are directly exposed to the range of huge air shock wave damage once the blockage arch collapses, and the personal safety of the operators cannot be guaranteed.
