Description
Technical Field
The invention belongs to the technical field of underground mining, and particularly relates to a mining method for underground mines by combining a segmented open stope method and a staged open stope method, which is particularly suitable for thick and large steeply inclined ore body underground mines with extremely broken surrounding rocks.
Background
The open stope mining method is widely used in underground mining, and is a method for dividing ore blocks into chambers and pillars for mining, and includes a comprehensive mining method, a chamber pillar mining method, a shrinkage mining method, a segmental open stope method (a segmental chamber method), a stage open stope method (a stage chamber method) and the like. The method comprises the steps of dividing an ore block into sections along the inclined direction, dividing the ore block into an ore room and an ore pillar in each section, arranging a section transportation drift to form a section rock drilling ore breaking and an independent stoping unit for section ore removal, stoping the ore room first and then the ore pillar, and processing a goaf simultaneously; the stage open stope method is suitable for extremely inclined thick and extremely thick ore bodies, the ore rooms are divided along the extreme full height, ore removal is only carried out on the lower part of the stage by a bottom structure, and the method is divided into a sectional rock drilling stage open stope method and a stage rock drilling stage open stope method according to different rock drilling modes.
In the design of the underground mine mining method, the vertical deep hole stage open stoping subsequent filling method mining is usually adopted for thick and large steeply inclined ore bodies, the vertical direction arrangement of the ore room ore bodies is carried out in a mode of separating three mining and one mining, and the purposes of mining and cutting work Cheng Shao, safe operation, high resource recovery rate and the like are achieved. For example, the south of the Zhou oil mill iron ore belonging to Cheng-Ore Limited liability company of Jinri Ri, anhui has a large ore body thickness and an average thickness of about 50m; the inclination angle of the ore body is 60-80 degrees. The design adopts a vertical deep hole rock drilling stage open stope subsequent filling mining method, and a chamber is arranged in a vertical ore body trend at three-mining-one interval.
Practice proves that when surrounding rocks are broken completely, the open-stope subsequent filling mining method cannot serve production well in the vertical deep hole rock drilling stage. Because the ore body has a certain inclination angle and the stoping sequence between stages is from bottom to top, the broken hanging wall surrounding rocks are difficult to keep stable after stoping of a stope is finished. At this time, mine enterprises usually adopt measures such as increasing ore pillars, reducing stope span, and strengthening hanging wall surrounding rock support to ensure safety. Because the standard chamber size of the stage empty field method is larger, the length of the chamber is the same as the thickness of the ore body, namely about 60m, the width is 15-20 m, and the height is the same as the height of the stage, namely 50-60 m generally. On the premise of such huge size, the effects of the various optimization measures are not obvious, and the mineral resources are seriously wasted.
In view of the above problems, there is an urgent need to develop and design a novel underground mining method and a stope arrangement structure with good safety, easy construction and high resource recovery rate.
