  • Design and fabrication of cable bolt for excavation in a fractured rock 
    Dhanawardana, YLC; Siriwardana, HDPM; Henderson, SH; Kumara, HMCP; Indika, KAS; Dharmaratne, PGR; Welideniya, HS; Rohitha, LPS [Conference-Full-text]
    In fractured rock masses, large excavations have an unsupported stand-up times less than the minimum time required to support the roof after the excavation. Therefore, the principal objective in the design of a support ...
  • Designing suitable mining method and processing plant for Kukurampola magnetite ore body 
    Amarasekera, HM; Sajirupan, S; Senanayake, IP; Sirisoma, RHANC; Chaminda, SP; Rohitha, LPS; Welideniya, HS [Conference-Full-text]
    Evaluation of mining methods for the exploitation of Kukurampola ore body is considered in this report. Minerals take millions of years to form, but exploitation takes only few decades. Therefore, mineral deposit is a ...
  • Ground vibration and air blast overpressure assessment using scaled distance 
    Sivarajan, V; Kumara, KLDS; Hearath, HMSD; Nanayakare, NWP; Welideniya, HS; Weerawarnakula, S [Conference-Full-text]
    In recent years there was a noticeable developmental activity, especially in industrial as well as construction sectors such as roads, harbours, condominiums etc. This has enhanced and developed aggregate industry and ...

    Kalubowila, KDLSSP; Gomes, DGNM; Arundathie, KWDD; Dharmarathne, WGAD; Kumara, WAP; Welideniya, HS; Fernando, WLW [Conference-Full-text]
    Manufactured sand is considered as an alternative to match the rising demand of river sand in the construction industry. The basic concept is to crush Quartzite, the source rock to produce sand. This report focuses on ...
  • Tunnel design for fractured rocks and suitable support selection 
    Senthilkumar, M; Senadhira, AMADM; Giriwaksan, S; Welideniya, HS; Dharmaratne, PGR [Conference-Full-text]
    This research focused on design of a tunnel in highly fractured rocks, and to propose suitable support classes, based on the study carried out at the Upper Kotmale Hydro Power project location. The necessity arises in ...
  • Ventilation of underground workings and improvement of comfort levels 
    Hewage, SC; Rajapakse, RAAC; Rathnayake, RMD; Prasanna, EAP; Dissanayake, DMAK; Dharmaratne, PGR; Welideniya, HS; Rohitha, LPS [Conference-Full-text]
    Ventilation of underground mines is required to dilute and hazardous gases, control heat and provide oxygen for workers and machinery. Kahatagaha- Kolongaha mines, Dodamgaslanda was selected for the present study as ...
