Synopsis

This webinar provides an introduction to the recently revitalized mine heritage, the Lin Ma Hang Mine, a recently completed project directed by the Civil Engineering and Development Department (CEDD).

The revitalization of the 19th-century Lin Ma Hang Mine and surrounds provides a unique demonstration of innovative geotechnical investigation and design for conservation and educational purposes in a country park. The restoration of the cavern complex and nearby area aimed to improve the safety of the old heritage mining complex for the public, whilst enhancing the recreational value of the newly designated Robin's Nest Country Park. 

The project is a unique example of historical and scientific preservation and safety-based enhancement for the public and community. From the outset, assessment of the engineering geological and geotechnical conditions of the natural terrain, drainage, anthropogenic influences and the rock mass related to the ore body were key for prioritizing the geotechnical works. Insights gained from the challenges encountered during the background study, investigations, design and construction phases will contribute valuable experience for future projects with similar sensitivity in Hong Kong and elsewhere. 

All essential elements in helping establish a balance between making “safe for purpose” without compromising the integrity of the heritage and scientific character of the site.
