Policy forced: Invisible revolution to support industries

At the national level, the hard indicator of "the intelligent production capacity of coal mines shall not be less than 60% by 2026" is becoming the baton to support product upgrades. In Guizhou, 77.7% of small mines are facing the transformation of "technology-driven". The popularization of AI video surveillance and intelligent early warning systems directly require support equipment to have data interaction capabilities - traditional steel brackets are evolving towards "perceptual terminals". The special demand for "low-temperature-resistant and hypoxia-resistant sensors" in Tibet's high-altitude mining areas has given rise to technical branches that adapt to supporting products and extreme environments.The differentiated layout of local policies is particularly critical. As a major bidding province (15,063 times in the first quarter), Shanxi's "risk monitoring and early warning network" that focuses on promoting its intelligent transformation requires the support system to be embedded with stress sensors to achieve real-time monitoring; Anhui has made it clear in the bidding for mining and construction projects (4,542 times) that new tunnels must use intelligent support equipment with attitude self-adjustment function. This dual-wheel drive of "policy + market" has expanded the technical threshold of supporting products from simple mechanical properties to multi-dimensional standards such as data interfaces, environmental adaptability, and intelligent response.

Technology Fusion: The leap from "static bearer" to "dynamic response"

Research on slope stability of the key laboratory of coal fine exploration and intelligent development provides a new methodology for support technology. The slope parameter identification technology based on the drone laser point cloud (level accuracy is better than 6cm), which not only accurately calculates key data such as step height and slope angle, but also forces the support system to develop a dynamic adaptation capability of "retrieval and support".The popularization of the "one tow and three drilling rig" model of the excavation and anchorage integrated machine (single shift drilling efficiency is improved by 25%) requires the sharing of support anchor rods and tunneling equipment to hydraulic systems. Traditional mechanical anchorage is being replaced by the integrated process of "drilling-support-monitoring". The impact ground pressure monitoring device developed by the Academy of Coal Sciences (equipped with more than 10 sensors), makes the support products the core node of the impact ground pressure warning system. When a torque abnormality is monitored, the intelligent support can start the pressure relief program in 0.3 seconds. This closed-loop capability of "perception - decision - execution" redefines the safety value of the support products.

Market reconstruction: Head effect and segmentation opportunities coexist

Bidding data reveals profound changes in the industry. In the high-frequency procurement of transportation equipment (761 times) and infrastructure systems (763 times), the leading enterprises in the industry included intelligent support in the required list. At the same time, they also made it clear in the bidding of mining equipment (349 times) that the boring machine must be equipped with intelligent anchor machines. The centralized procurement of this large mining group is accelerating the Matthew effect of supporting the industry - leading companies with digital transformation capabilities have a market share of 3-5 percentage points higher than traditional manufacturers.

Opportunities in segments are also worth paying attention to. The surge in ecological restoration and governance bidding (6577 times) has promoted the rise of green support technology. The biodegradable anchors used by Guilaizhuang Gold Mine have obtained additional weighting in the ecological restoration score; explosion-proof support robots dedicated to karst landforms have opened up the blue ocean market in the southwest mining area. What is more disruptive is the application of digital twin technology. Copper mine simulates support stress distribution through three-dimensional modeling, reducing material loss by 18%. This "virtual debugging + physical application" model is rewriting the industry cost structure.

Future Map: When support becomes a neural network for intelligent mines

The ultimate form of mining support products may be the "bone and nerve" of smart mines. The integrated application of lidar and vision cameras will enable the bracket to have environmental modeling capabilities; the implantation of high-precision navigation technology can realize the autonomous movement and precise positioning of the support equipment.

The pain of industrial change has already emerged. Small and medium-sized support enterprises face the choice of "either intelligent or integrated", while large enterprises need to break through the cross-border barriers of "mechanical manufacturing + software algorithm". But what is certain is that when policy dividends and technological breakthroughs resonate with market demand, this traditional industry that carries the bottom line of mining safety is standing at a historical turning point from "silly, big, black and thick" to "wisdom and agile".
