Construction of the “Backbone” of the Gengban Coal Mine’s Conveying System
(Mengban Coal Mine Ventilation and Safety Section -- Huang Yong)
The foundation work for the main inclined shaft belt conveyor at Gengban Coal Mine is being carried out by Zhongyuan Construction, with Jiangxi Tongji Construction Project Management Co., Ltd. serving as the supervising entity. Following thorough technical preparations, the mechanical roar of equipment echoes at the shaft entrance, and the entire construction area has been cordoned off with yellow tape. On a site composed of loess mixed with gravel, an excavator extends its steel arm, precisely excavating within the red line marked by a total station. —— Here, a new structure is about to rise, supporting the entire conveyor system of the Gengban Coal Mine. “ spine ”— Foundation for the head of the belt conveyor at the main inclined shaft entrance.

The belt‑support foundation at the head of the main inclined shaft is the core load‑bearing structure of the coal mine’s hoisting and conveying system; its construction quality directly affects the stable operation of the belt conveyor and the overall production efficiency of the mine. To ensure that the foundation possesses adequate strength, stiffness, and stability, it is essential to strictly adhere to construction codes, meticulously control key technical aspects at each stage, and rigorously implement safety management measures.
Prior to construction, technical personnel shall convene all team members for a detailed review of the design drawings, thoroughly interpreting the design documents to clarify the foundation’s dimensional parameters, concrete strength grades, reinforcement detailing requirements, and the locations of embedded components. In addition, based on the actual site-specific geological conditions, a dedicated construction plan shall be developed, specifying technical parameters and operational standards for key processes such as surveying and layout, excavation of the foundation pit, rebar tying, formwork support, and concrete placement. Furthermore, technical briefings and safety training shall be conducted for all construction workers to ensure they are fully familiar with the construction sequence and quality‑acceptance criteria.

Subsequently, surface excavation, pile driving, formwork erection, and concrete placement and curing are carried out. Each step undergoes rigorous inspection and acceptance. The construction of the belt‑conveyor foundation at the head of the main inclined shaft requires both technical precision and meticulous process control; from preliminary preparation to final curing, every stage strictly adheres to applicable codes and standards. , In summary, the foundation construction for the main inclined shaft belt conveyor at Gengban Coal Mine is currently under intensive execution. Only by strengthening technical briefings, rigorously controlling material quality, and refining construction procedures can we ensure the quality of the foundation works and lay a solid groundwork for the mine’s long-term, stable production.
